kernel32/tests: Extend the tests for load/unload debug events on Wow64.
Showing that: - load events for 64bit DLLs are generated for a WOW64 process. - unload events for 64bit DLLs are not generated for a WOW64 process (as any other unload event on process teardown). - a 32bit startup exception is generated as well (with a specific exception code)
