[Emus] Add standalone Flycast emulator (#79)

* Add standalone Flycast emulator, significant performance improvement compared to libretro core
Credit to tomato6333 from RGH Discord for compilation
* Add libretro label to flycast 16:9
* Update flycast binary
Flycast data and config dirs are now defined by environment variables $FLYCAST_DATA_DIR and $FLYCAST_CONFIG_DIR
* OpenGL support!
* Add config and data dirs
* Change atomiswave cpufreq name
* Change performance profile
Ondemand governor causes framedrops due to flycast being cpu-heavy
* Add jump pack support and use bios folder
* Fix missing leading slash
* Add emu.cfg
