This patch adds a new feature to lit. We can now define `setup` and `teardown` routines that will be run before the whole test suite starts and after it completes, respectively.

The primary use case for this feature is running std::filesystem tests in libc++ on a remote target. There, we need to copy test inputs to the target machine via SSH, run the tests on those inputs, and then, after all the tests have been run, we need to remove those test inputs from the target machine.
