Scott Graham 48abd4a60f Add CRASHPAD_CHILD_TEST_MAIN() helper for multiprocess tests
Extends MultiprocessExec to support running functions registered via
CRASHPAD_CHILD_TEST_MAIN() as the main of a new child process.

Additionally, implements Fuchsia exit code checking, and adds a
CRASHPAD_CHILD_TEST_MAIN()-based test for that.
