add more TAS support

[dananothername]

What should happen

many people request TAS features
PPSSPP should have a button for

• rewind frame and not rewind last save state
• a pannel or something for input recording and then to switch for reading like in bizhawk
• while input recording can be enabled before starting the game
  here the emulator should store the same hash to keep the same RNG (random numbers generator ) this is very important for the TAS match each time opening the game
  a note : while encoding the frame rate was set to 30 fps while playing 50 fps it gives a weird behavior like the game glitch frame backward

Who would this benefit

the TASers from TASvideos and Reddit

Platform (if relevant)

Windows

Games this would be useful in

any game

Other emulators or software with a similar feature

-retroarch support some of TAS features( tbh it needs to be easier )
-using ppsspp in libTAS in pain and i don't recommend it
but you can see how the emulator work with TAS and make ppsspp work like it

• the best emulator for TAS is bizhawk
  tbh i want a ppsspp core in libTAS

Checklist

• Check the latest git build in case it's already implemented.
• Search for other requests of the same feature.
