Trim whitespace in MTP --test-modules expressions

[Copilot]

Bug Fix

What was the bug?

dotnet test (MTP) accepted semicolon-delimited --test-modules glob expressions, but did not trim surrounding whitespace per segment.
As a result, expressions like "**/*.Platform.mstest.exe; **/*.Modules.mstest.exe" could ignore later patterns, which also impacts folded YAML argument formatting.

How did you fix it?

• CLI parsing behavior

  • Updated MTP module-pattern parsing to normalize each semicolon-separated token before matching.
  • Current flow: split on ; → trim each token → drop empty entries → pass normalized patterns to the glob matcher.

• Regression coverage

  • Added an integration test in GivenDotnetTestBuildsAndRunsTestBasedOnGlobbingFilter that passes a whitespace/newline/tab-containing --test-modules expression with multiple patterns and verifies both test modules are included in execution.

Example

dotnet test --test-modules "**/*.ModuleA.mstest.exe;
  **/*.ModuleB.mstest.exe;
	**/*.ModuleC.mstest.exe"

With this change, each pattern is trimmed before glob evaluation, so all intended modules are matched.

Pull request overview

Fixes dotnet test (MTP) --test-modules parsing so semicolon-delimited glob patterns are trimmed per-token before matching, ensuring patterns with surrounding whitespace (including newline/tab) are honored consistently.

Changes:

• Trim each semicolon-separated --test-modules pattern token and drop empty tokens before passing patterns to the glob matcher.
• Add an integration test validating that whitespace/newline/tab around semicolon-delimited patterns still matches all intended test modules.
• Includes an unrelated SARIF formatting/encoding diff that should be reverted (see PR comment).
