Snes9x - Add option for overclock Super FX at 20 MHz and update selectable options (Taken from niuus' Snes9x RX) (#1003)

Browse Source 
* Add option for overclock Super FX at 20 MHz and update selectable options (niuus)

Add an option for overclock Super FX 1 / GSU-1 (MARIO Chip) games to 20 MHz, taken from @niuus' fork of Snes9xGX, called Snes9x RX.
Overclocking to 40 MHz/60 MHz are unstable for these games that used the SFX GSU-1 chip, and makes it unplayable due to too fast speed, so this modification adds this 20MHz overclock option.

* Forgot to update option order for avoid conflict between menus
