Support Bazel's TEST_PREMATURE_EXIT_FILE and add it to CLI as well

Browse Source 
This tells Catch2 to create an empty file at specified path before
the tests start, and delete it after the tests finish. This allows
callers to catch cases where the test binary silently exits before
finishing (e.g. via call to `exit(0)` inside the code under test),
by looking whether the file still exists.

Closes #3020
