Implements the [[patches.func]] feature that was mentioned as planned
in the README. This allows defining recompiler hooks in the config file
that call specific functions at designated points.
Added FunctionHookDefinition struct supporting two modes:
- before_call: Hook at function entry
- before_vram: Hook at specific instruction address
Hook functions receive rdram and recomp_context parameters for full
access to registers and memory. The implementation reuses the existing
function_hooks map so it integrates cleanly with the current pipeline.
Includes validation for nonexistent functions, invalid addresses, and
misaligned vram values with helpful error messages.
