Migrate inline asm call sites to hook.call()

Replace hand-written inline asm blocks with hook.call() typed function
pointer dispatch across 10 files. Also migrates 4 D3D9 COM vtable
NULL-dispatch blocks using ?*anyopaque optional pointers.

Net removal: ~350 lines of inline asm replaced by single-line calls.
