vba-next-switch v0.7 Cheat support

This is probably going to be the final version of VBA-next. But don't worry, we're working on bringing another offspring of VBA, VBA-M, with a lot of feature than retroarch's VBA-next to the Switch.

Changelog:

• Cheat support. They can be directly entered from the emulator, just enter the cheats menu from the pause menu.
• Fullscreen UI in docked mode(though the implementation isn't optimal, also currently not tested)
• Some minor improvements and adjustments, seriously

vba-next-switch v0.6 Huge UI improvements

Changelog:

• Complete UI overhaul. Now it looks almost native!
• Setting to offset the real time clock

Again thanks to @dene-, who's responsible for the UI improvements and @jakibaki who's our expert for RTC and saving.

vba-next-switch v0.5

Changelog:

• UI improvements
• Fast forward is now on the R button
• There's an option to swap the function of the L and R buttons with ZL and ZR's function.
• Some minor adjustments and bug fixes(see the commits made)

Thanks to @dene- who contributed most of this release.

vba-next-switch v0.4

• Reduced lag from emulator and main thread image synchronisation
• Increased filename buffer
• Filenames are sorted alphabetically

Note: this release was originally named 0.3b, but since Github sorts the releases weirdly, I decided on renaming the release

vba-next-switch v0.3

Changelog:

• Better audio in almost all situations
• More robust string and path handling
• Added autosaving
• Added settings menu (press Minus to open it)
• Added screen scaling (Options: Nearest Integer, Nearest Fullscreen, Bilinear Fullscreen. The last one is a bit slow so I don't recommend it)
• Added RTC support
• Fixed #8 (analog sticks can be disabled via the settings)

Thanks to @jakibaki, who contributed both the autosaving and the RTC support
