This PR adds end-to-end dotnet test integration tests for all Apple platforms (iOS, tvOS, Mac Catalyst, macOS) using the MTP (Microsoft Testing Platform) test templates.

Changes

  • tests/dotnet/UnitTests/DotNetTestTest.cs: New parameterized test that creates a project from dotnet new <template>, replaces the generated tests with a single passing test, and runs dotnet test.
  • tests/common/DotNet.cs: Added test verb support to DotNet.Execute.

The test reads the MLAUNCH_PATH environment variable to override the mlaunch binary for mobile platforms (iOS/tvOS), enabling testing with the MTP-enabled mlaunch build.

Depends on mlaunch MTP support: https://devdiv.visualstudio.com/DevDiv/_git/macios-mlaunch/pullrequest/734978

Create DotNetTestTest that runs 'dotnet test' on projects created from
the iostest, tvostest, maccatalysttest, and macostest templates. This
verifies the MTP (Microsoft Testing Platform) pipeline works end-to-end,
including the --server/--dotnet-test-pipe argument passthrough via
RunArguments.

Also add 'test' as a supported verb in DotNet.Execute.

macOS and Mac Catalyst don't use mlaunch (they use 'open' via
Desktop.targets), so MTP support requires a different approach.
Comment out those test cases for now.

Also skip the /v:diag and /consoleloggerparameters workaround args
when the verb is 'test' to prevent them leaking through to the MTP
test runner via RunArguments.
