Use hook.cc.* aliases and migrate remaining hook.fastcall calls

Browse Source 
Replace all local calling convention declarations (const fc/tc/sc)
with hook.cc.fastcall/thiscall/stdcall from zhook. Migrate remaining
17 hook.fastcall() inline asm call sites to hook.call() with typed
function pointers.
