Now left and right joycons have the same priority (meaning both needs to be supported by the game).
Explanation of the new heuristic:
Assign left joycons to even player indices and right joycons to odd player indices.
We do this since Captain Toad Treasure Tracker expects a left joycon for Player 1 and a right Joycon for Player 2 in 2 Player Assist mode.
This is more representative of what actually occurs, as web does support remote URLs which wouldn't need a romfs callback. This paves for easy future support of this with a call like 'OpenPageRemote' or similar.
This is a function that definitely doesn't always have a non-modifying
behavior across all implementations, so this should be made non-const.
This gets rid of the need to mark data members as mutable to work around
the fact mutating data members needs to occur.
Default implementation will return "yuzu" for any string. GUI clients (or CLI) can implement the Frontend::SoftwareKeyboardApplet class and register an instance to provide functionality.
