feat(test): add support for testing against wow.exe

[heinermann]

• Addresses discrepancies in some return types and calling conventions.
• Provides a mechanism to run tests against a Wow.exe. More versions can be added following the same format (probably with some tweaks).

1. Need to fix passing of cmdline args to the test suite.
2. Need to move WoW 3.3.5a specific stuff out into its addressmap file (i.e. specifying WinMain address, Sleep pointer).
3. Fix MSVC dependency (inline asm) to just write the bytes instead. seems annoying w/e
4. Include some other versions that I might have to be able to run more tests.

Going to split the calling discrepancies into a separate PR.
