WIP: Drop asm usages in game_sa

[sbx320]

Some initial work on automatically rewriting game_sa's inline asm to proper C++ calls via a custom clang-tidy plugin.

See https://github.com/sbx320/mtaasmrewriter for source

Rough approach is:

• Find all __asm statements
• Collect all push instructions (arguments)
• Look for a mov ecx, [something] instruction (__thiscall indicator)
• Look for a mov [something], [something] instruction (return value)

Then rewrite the statement to a function type declaration and a function call.

Current issues:

• Does not support other asm instructions (e.g. lea is used in some places)
• Does not properly escape prefix-less hexadecimal numbers (e.g. push 0B73710h is mapped to a function argument 0B73710h which is a base-2 number
• If multiple function calls are used, the type declaration collides due to duplicate names
• clang formatting is disabled
• needs to be on master, not on 1.6.0
