[dds/dap] Improve stack frame rendering + fix bad paths in tests
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). Fixes https://github.com/Dart-Code/Dart-Code/issues/4573, Change-Id: I6c1c3ab69915eca9a1eeef5dcba7f1eb558086de Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/311842 Reviewed-by: Ben Konyi <bkonyi@google.com> Commit-Queue: Ben Konyi <bkonyi@google.com>

# 2.9.2
|
||||
- [DAP] Fixed an issue that could cause breakpoints to become unresolved when there are multiple isolates (such as during a test run).
|
||||
- [DAP] Fixed an issue where stack frames parsed in test failures could produce incorrect absolute paths in the `source.path` field if the working directory of the debug adapter did not match that of the launch/attach request.
|
||||
- [DAP] A new configuration option `bool? allowAnsiColorOutput` can enable using ansi color codes in `Output` events to improve readability of stack traces (fading out frames that are not user code).
|
||||
|
||||
# 2.9.1
|
||||
- [DAP] A new configuration option `bool? showGettersInDebugViews` allows getters to be shown wrapped in Variables/Evaluation responses so that they can be lazily expanded by the user. `evaluateGettersInDebugViews` must be `false` for this behaviour.
