API: Implement Native Hook/Patching API

[noahc3]

Much of Affinity is implemented in native code (libpersona.dll, libgeometry.dll) - it would be very helpful to have a native code hooking API to patch native functions. Right now APL can only be used to patch managed libraries, if devs want to patch native functions they need to bring their own solution. It would be better to provide a standardized native patching API to improve compatibility between mods.

This would likely be used by #8 as a test/example.

Having trouble getting this working reliably. To get #8 sooner than later, will deprioritize this for a future release and instead just bundle the updated d2d1.dll with WineFix (either embedded resource or in the zip/tar)
