This is a step towards detaching bodies of closures/local
functions from the enclosing functions in TFA, so closures
could be analyzed separately.
Also, this change allows TFA to accumulate types of captured local
variables among all invocations.
On a large Flutter app, this change doesn't cause noticeable compilation
time or snapshot size changes.

The main purpose of the low-level [PortMap] is to coordinate between
ports being opened & closed and concurrent message senders. That's the
only thing it should do.
Each isolate owns [ReceivePort]s. Only the isolate mutator can create
ports, delete them or change their "keeps-isolate-alive" state. Right
now it requires going via [PortMap] (which acquires lock) and
[MessageHandler] (which acquires lock) to change the
"keeps-isolate-alive" state of a port.
We'll move information whether a dart [ReceivePort] is closed and
whether it keeps the isolate alive into the [ReceivePort] object itself.
=> Changing the "keeps-isolate-alive" state of the port no longer
requires any locks. We could even avoid the runtime call itself in a
future CL.
Isolates are kept alive if there's any open receive ports (that have not
been marked as "does not keep isolate alive"). This is a property of an
isolate not of the message handler. For native message handlers we do
have a 1<->1 correspondence between port and handler (i.e. there's no
"number of open ports" tracking needed).
=> We'll move the logic of counting open receive ports and ports that
keep the isolate alive to the [Isolate].
=> We'll also remove locking around incrementing/decrementing or
accessing the counts.
=> The [IsolateMessageHandler] will ask the [Isolate] whether there's
any open ports for determining whether to shut down.
=> For native ports, the `Dart_NewNativePort()` & `Dart_CloseNativePort()`
functions will manage the lifetime (as their name also suggests).
Overall this makes the [Isolate] responsible for creation of dart
[ReceivePort]s and tracking whether the isolate should be kept alive:
* Isolate::CreateReceivePort()
* Isolate::SetReceivePortKeepAliveState()
* Isolate::CloseReceivePort()

All uses of `PortMap::Create()` would call `PortMap::SetPortState()`
after creating the port. To avoid acquiring the port map lock twice, we
can initialize the state already in `PortMap::Create()`.
Additionally we fix an existing issue by making the isolate's main port
a control port (instead of leaving it as a `kNewPort`).
As a side-effect we'll no longer have any allocated ports with state
`kNewPort`.
We also remove the unused `PortMap::IsLocalPort()`

Originally we didn't use the LSP Request/Response classes, and just exposed the handlers through the legacy request/response.
However there were some mismatches (such as legacy protocol always returns Map<String, Object?> but some LSP requests return Lists, LSP using int|String IDs, and LSP having numeric error codes that don't match legacy string error codes).
This change uses LSP's request and Response by wrapping them inside a standard (legacy) handler. The LSP-over-Legacy handler has become a standard handler, and the params contain an "lspMessage" field that holds an LSP message, and the result contains an "lspResponse" field that contains an LSP response.
If an LSP handler returns an error, it will be returned as an error inside the LSP response, which will be in a _successful_ legacy request (since that's how we can return an LSP response - as the result).

I was trying out DCM and it found this bogus condition.
The only instance I can find where it triggered was adjacent interpolations in strings, and the fallback code (which compares by token type) would handle it correctly, but in case there are other cases (now or in future), I've added an assert to try to avoid reaching the fallback in case it doesn't produce the desired result.

Several changes are made:
- createDartExport now does not export methods that define type parameters.
- createStaticInteropMock adds conformance checks to make sure implementing
members can handle all possible values of a type parameter in an interop
member. An error is added to reduce confusion around this.
- Export creator now uses dart:js_interop_unsafe for a lot of its lowering
as the dart:js_util equivalents are buggy when it comes to calling exported
functions in JS with JS types.
- Small code changes are added to backends to handle the above changes.
