Build/Test Tools: Add path detection when running GitHub Actions on pull_request.

This change adds a list of paths to check when determining which workflows to run on `pull_request`. This will prevent certain workflows from running unnecessarily when the files updated are not related to the tests and checks being performed.

Props peterwilsoncc, johnbillion.
Fixes #52667.
