Add support for "RETRO_ENVIRONMENT_SET_CORE_OPTIONS_UPDATE_DISPLAY_CALLBACK" environment callback #200

Closed jdgleaver closed 2 years ago

jdgleaver commented 2 years ago

This PR is a test case/demonstration of the new RETRO_ENVIRONMENT_SET_CORE_OPTIONS_UPDATE_DISPLAY_CALLBACK frontend environment callback.

It allows the Show Gameboy Link Settings option to update the frontend options menu in real-time, without toggling the Quick Menu (on supported frontends)

The PR also cleans up the mess left over from the recent core option update/revert.
