kernel32/tests: Extend the tests for load/unload debug events on Wow64.

Browse source 
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)
