[Core] Convert Dynamic Macro to a Core Feature (#5948)

* Convert Dynamic Macro to a Core Feature

This imports the code from Dynamic Macro into the core code, and handles it, as such.

This deprecates the old method but does not remove it, for legacy support. This way, no existing user files need to be touched.

Additionally, this reorganizes the documentation to better reflect the changes.

Also, it adds user hooks to the feature so users can customize the existing functionality.

Based heavily on and closes #2976

* Apply suggestions from code review

* Cleanup based on feedback

* Add short-form keycodes and document them

- add short-form keycodes to quantum/quantum_keycodes.h
- document the new aliases in docs/feature_dynamic_macros.md

* Add Dynamic Macros section and keycodes to docs/keycodes.md

* Make anti-nesting optional

* Add documentation for DYNAMIC_MACRO_NO_NESTING option

* Fix Merge artifacts

* Fix formatting typo in docs

Co-Authored-By: James Young <18669334+noroadsleft@users.noreply.github.com>

* Remove DYNAMIC_MACRO_RANGE as it's not needed

* Fix includes and layer var type

+Note, that direction indicates which macro it is, with `1` being Macro 1, `-1` being Macro 2, and 0 being no macro.

+* `dynamic_macro_record_end_user(int8_t direction)` - Triggered when the macro recording is stopped. 
+
+Additionally, you can call `dynamic_macro_led_blink()` to flash the backlights if that feature is enabled.
