Add support for inline hooks (and extended inline hook contexts)

- [ ] Inline hooks (probably `exl::util::Hook::InlineHook`)
- [ ] Extended inline hook contexts
    - The current 29 GP registers
    - Stack pointer
    - All 32 FP registers
- [ ] Ability to hook with only the limited context (`InlineCtx`) or the extended context (`ExInlineCtx`) because the extended context is over 3x the stack usage
