Scott Graham 0403602393 Fix CrashpadInfoSizes_ClientOptions/CrashpadInfoSizes_ClientOptions
These tests needed to be updated to expose CrashpadInfo in the same way
as the main CrashpadInfo g_crashpad_info is found on
Linux/Android/Fuchsia.

Unfortunately, while the tests pass on Fuchsia when run in isolation,
the implementation of dlclose() on Fuchsia currently does nothing. So,
if the full test suite is run, there's interference between the test
modules (i.e. the values in _small vs. the values in _large), so the
tests fail.

I filed ZX-1728 upstream about this to see if it might be implemented,
or if the test will need to spawn a clean child to do the module load
tests in.
