input_common/tas: Base playback & recording system

The base playback system supports up to 8 controllers (specified by `PLAYER_NUMBER` in `tas_input.h`), which all change their inputs simulataneously when `TAS::UpdateThread` is called.

The recording system uses the controller debugger to read the state of the first controller and forwards that data to the TASing system for recording. Currently, this process sadly is not frame-perfect and pixel-accurate.
