Changing TestAll.ps1 script to run tests locally with filtering

[guimafelipe]

When working on WinAppSDK, we want to be able to easily run tests to check if our changes are breaking anything or introducing any regressions.

Now, the TestAll.ps1 was changed to also work running locally and passing arguments to filter the tests and optionally build them.

A microsoft employee must use /azp run to validate using the pipelines below.
