ci: run xunit.v3/MTP test hosts directly on .NET 10 (fix broken dotnet test VSTest path)

- MTP (xunit.v3) on .NET 10 rejects the old dotnet test VSTest flags
  (--collect XPlat Code Coverage / --logger trx / --blame-hang) on all 3 OS.
- CI now invokes each MTP test executable directly with -filterVSTest and
  -result-trx (verified locally: 1373 tests, 0 failures, TRX emitted).
- Added Microsoft.Testing.Extensions.CodeCoverage 17.10.1 to CPM + the four
  test projects so MTP coverage is available. The VSTest coverage-collect step
  was removed from ci.yml; coverage will be re-enabled once a working MTP
  coverage flow is configured.
- Fixed Directory.Packages.props XML comment (no -- in a comment).
