#158 Per-game controller keys binding profiling

[Korwin]

I propose adding support for exporting and importing key mapping profiles for modern game controllers and specific games. Moreover, with the ability to automatically load a profile file if it is found for a game in the same folder where the game file is located, and the controller model in the profile matches the model of the connected controller. If the controllers are different, a suggestion should be given to load the profile for checking it and, if necessary, additional configuration.

In the future, this may serve as the basis for an online controllers layouts profile database, similar to that in Steam Workshop (see screenshot).
