Various test fixes

[bart-vmware]

Backported changes from experimenting with running tests on MTPv2.

• Fixes test failures when running in WSL2 on Ubuntu
  Make assertions ignore differences in line endings, originating from multi-line raw string literals. The code is compiled using the Windows newline separator, which differs from the newline separator used when executing on Ubuntu.
• Explicitly target VSTest mode in xUnit
  Reference xunit.v3.mtp-off, so we don't need DisableTestingPlatformServerCapability=false anymore.
  Edit: Reverted back to reference xunit.v3, because xunit.v3.mtp-off breaks running tests in WSL.
• Adds a workaround to prevent taking a dump on hanging/crashing test on macOS from timing out
• Reduce test hang timeout from 3 to 1 minutes
  A hanging test on all three frameworks took 9 minutes, leaving insufficient time to upload the dump in component builds (which time out after 15 minutes).
• Always write test output to a subdirectory, instead of the checkout root
• Run tests for all frameworks in a single command (the bug ignoring TestTfmsInParallel has been fixed)
• Replace skipFilter with a boolean, which separates intent from implementation
• Run memory dump tests only for Management.Endpoint.Test project to speed up runs
• Add diagnostics to investigate intermittent hostname lookup failures on macOS
  Guarded by an environment variable that is set in GHA, to not influence existing production behavior.
