This adds two custom requests to the DAP-over-DDS handler to translate between VM/DAP instance IDs:
- $/createVariableForInstance (String isolateId, String instanceId)
- $/getVariablesInstanceId (int variablesReference)
Because DAP's variables request only fetches _child_ variables (eg. fields) but we'd likely want to align the top-level string display of a variable, the wrapped variable will first be returned as a single variable named "value", which contains both the string display value and also a variablesReference to then get the child variables (usually invoked when expanded).
These methods currently live directly in the DDS DAP adapter since I figure they're only useful for clients using the VM Service, but we can move them to the base adapter if in future this turns out to not be the case.

We used to generate our own thread ID starting at 1 and counting up. There was always a 1:1 mapping from a DAP thread to a VM Isolate. With this change, we always use the Isolate number as the thread ID which makes it easier for tools using both VM Service and DAP at the same time.

This fixes a bug where we'd produce the wrong absolute path for stack frames that had absolute paths (because `package:stack_trace` uses `path.absolute()` on them).
It also adds support for making stack frames in printed stack traces faded if they are not part of the users own code. This is something the legacy DAPs did. I've also made it possible to perform this stack parsing on non-error events because I'd like to use it on Flutter structured errors (again, something we supported in legacy adapters and was missing here).

When there are multiple isolates, we may get breakpoint responses/events like this:
- Request/Response to add breakpoint to Isolate 1
- Request/Response to add breakpoint to Isolate 2
- BreakpointAdded for Isolate 1
- BreakpointResolved for Isolate 1
- BreakpointAdded for Isolate 2
Because Isolate 2 did not load the script, the last breakpoint was never resolved. However because the breakpoint ID matched, we would forward this event to the client and un-resolve the previously resolved breakpoint. This would result in odd behaviour in VS Code.
Additionally, the VM may return the same BM breakpoint ID for what the client thinks are two breakpoints (they are on different lines, but resolve to the same location) so when we get a resolved breakpoint, we need to handle both:
- Client breakpoints that have already been transmitted
- Future client breakpoints that may resolve to this same VM breakpoint
The previous code assumed that a BreakpointResolved event could be handled just once. Either for an existing breakpoint, or a future one.
This change swaps from storing queued events to storing the resolution information for each breakpoint, and it does this even if there was an existing breakpoint (in case the breakpoint is reused in future).

The existing 'evaluateGettersInDebugViews' evaluates getters eagerly which can have side-effects. This adds a setting that allows showing getters in a way that can be shown lazily instead.
I added a new setting (instead of just making evaluateGettersInDebugViews=false be lazy) to preserve the ability to have getters not shown at all (since some users are using that today and might prefer this over lots of lazy getters showing up).

When adding new breakpoints, DAP clients send a full new set of breakpoints which results in us removing and re-adding all breakpoints (for a file).
When we re-add a breakpoint that already existed, we would sometimes get the BreakpointAdded event _before_ the addBreakpointWithScriptUri request completed. We couldn't process the event because without the original request completing we could not map the VM breakpoint back to the clients breakpoint to generate the event.
This could result in resolution events being lost, and breakpoints becoming unresolved when you modified them (depending on timing).
This change collects queues and replays any BreakpointAdded/BreakpointResolved events that arrived when the breakpoint ID is unknown, and when `addBreakpointWithScriptUri` completes, it immediately processes any items in this queue.

This logic was inverted and could result in duplicate terminate requests being sent. Depending on timing, this request might be sent but not responded to (because the DA was already shutting down), causing a "Application terminated with pending terminate request" error.

When an isolate is paused, we store some data for things like variables, stack frames, etc. to round-trip an identifier to the client that it can ask about later.
Previously we never cleared these, so over time in a long debug session they could build up. The DAP spec says these references become invalid when execution is resumed:
> To simplify the management of object references in debug adapters, their lifetime is limited to the current suspended state. Once execution resumes, object references become invalid and DAP clients must not use them.
Because it's possible to resume one thread without another, I'm clearing up only the specific thread (isolate)s data when it resumes, rather than all of it.

Currently when the user configures a Dart CLI program to be run in the terminal, we ask VS Code to launch it in the terminal before we respond to the launch request. This (depending on settings) can cause VS Code to show the terminal and then switch to the Debug Console (which is both confusing and frustrating for users that opt-in to do this to access stdin of the terminal process).
This change reverses the order when using `runInTerminal` so that `launch` is responded to first.

Changes to support DAP in DDS introduced a subtle bug where we could send the `InitializedEvent` before the response to the `Initialize` request because `sendResponse` used a `Completer` and would delay adding the response to the stream until the next iteration of the task queue.
Although there were comments stating this order must be preserved, there were no tests that verified this and it breaks VS Code (https://github.com/dart-lang/sdk/issues/52222).
I've added tests for this, and changed how this works slightly so instead of using a `Completer` we pass in a "responseWriter" function that must write the response to the stream synchronously.
Since the DDS path isn't using events yet and it would require a little more refactoring, I've used a Completer there and added a TODO.
Fixes https://github.com/dart-lang/sdk/issues/52222.

There are two cases where we might be trying to resume an exited isolate:
1. Another debugger resumed the isolate and it exited before we got here
2. We were starting to resume an isolate but then the app was shut down so the isolate exited
Because of async code, we can never guarantee the isolate hasn't exited before we send this event, so the exception we throw should only ever be because the ID was invalid.

I'm unable to reproduce this, but there are probably many reasons an isolate could go away while we're doing this async work (such as the app shutting down or a restart). If it does, we should never throw because the results of configuring an isolate are not important if the isolate has gone.

There were two issues here:
1. During shutdown, when trying to unpause and resume all threads we could get "Service has Disappeared" responses if the app was already shutting down. These need ignoring. This is fixed with `_withErrorHandling` in preventBreakingAndResume.
2. The test teardown would always try to send a terminate request even if the test had already sent it, which could result in a second terminate request not being responded to (because the app shutdown before it could respond, because it had already had a terminate request). This is fixed by the teardown code only sending terminate() if it hadn't already been sent.
