Add support for built-in mods and convert D-Pad to a built-in mod (#567)

* Add embedded mod (using mm_recomp_draw_distance as an example).

* Update runtime after merge

* Experiment with removing the D-Pad.

* Add event needed for dpad as mod, revert remaining changes in built-in patches for dpad

* Add built-in dpad mod, add remaining event calls to input.c

* Add built-in mods readme

+# Built-in Mods
+
+This folder contains mods that are built into the Zelda 64: Recompiled project. Built-in mods behave like normal mods but are present in a clean installation of the project. They can be updated or downgraded by placing the .nrm file for the mod in the appdata mods folder in the same way a normal mod would be, which overrides the built-in version with the manually installed version.

+The list of built-in mods is as follows:
