This change adds functionality to the test runner script to search a directory tree for generated test metadata files, build up a graph of test groups, and run a user-specified list of groups with all of their dependencies. Tests are run through an external runner executable provided on the command line. The executable is called with the path to a unit test binary file. The old test runner functionality to run a single test directly from its binary path is maintained, but now uses a runner executable. This is configured in GN using the build variable "pw_automatic_test_runner", which replaces the functionality of "pw_unit_test_create_run_targets".
