Add options to zig compile options

Browse Source 
Support for compiling with raygui, raymath, and physac.
Also outputs the required headers.

Raygui should be located `../raygui` relative to the repo root
Physac should be located `../physac` relative to the repo root

This behavior matches options in the Makefile
