CMake: Add GCC/clang-specific options: ASAN, FORCE_COLORED_OUTPUT

Browse source 
-DASAN=ON   enables the Address Sanitizer (ASan), if supported
-DFORCE_COLORED_OUTPUT=ON  forces GCC or Clang to use colors in their
                           messages, useful when building with ninja

Both options default to OFF (though when building with make in a
suitable terminal, GCC and clang automatically use colors)

(no UBSAN, that requires hardlinking the game with the executable,
 which is not possible in the SDK..)
