CI for UI Tests Infrastructure Update (#88)

CLOSE
https://linear.app/sourcegraph/issue/CODY-2816/ci-for-visual-studio-integration-tests-based-on-vsixtesting

UI Tests infrastructure (`Cody.VisualStudio.Tests`) updated to allow running them, not only locally which were running fine from the very beginning, but also using GitHub Actions.

### Fixed threading issues only seen in GitHub Actions:
- VsixTesting runner exception: `Call was Rejected By Callee` ([more about it](https://learn.microsoft.com/en-us/previous-versions/ms228772(v=vs.140)?redirectedfrom=MSDN)), caused PlaywrightTestsBase.InitializeAsync() was called multiple times, which internally tries to call VS API, when XUnit was creating instances of all involved test classes
- Removed calls to VS API from TestBase constructor, which have the same effect as above

### Other Updates
- Added logging via XUnit logger, which calls our Logger internally and gives us detailed logs from tests (including all logs that are logged in the VS Cody output pane during run-time)
- Getting IDE to the front when "Start Window" appears (call to DismissStartWindow())
- WaitForAsync() waits maximum 2 minutes (for the chat loading)
- Added CollectionBehavior.CollectionPerAssembly and DisableTestParallelization = true for XUnit

Improved PlaywrightTestsBase:
  - Introduced SemaphoreSlim() for synchronization
  - Playwright related properties (Browser, Context, Page and Playwright) are now static
