InputKey does not use the correct keys when the keyboard layout is not QWERTY

[MatthieuHernandez]

I will explain with a simple example.
I used a AZERTY keyboard and I wand to do an undo on the map editor.
On this line, it is said that the undo action is on Ctrl + Z (which is also the normal shortcut on an AZERTY keyboard)

new KeyBinding(new KeyCombination(InputKey.Control, InputKey.Z), PlatformAction.Undo),

But on Osu!(lazer) I need to press Ctrl + W (as if my keyboard was forced to QWERTY).
The Z and W keys are reversed between QWERTY and AZERTY.

The weirdest thing is that I don't have the problem on osu!(stable).

I think the problem is related to this ppy/osu#11143.

P.-S I don't have the problem when I write text in osu! or when I maps my keys in the key configuration.

EDIT: The issue seems come from the InputKey.cs which hard-codes values.

I just found the exact source of the issue.
In the file SDL2Extensions.cs for the mapping of the keys, it is used SDL.SDL_Scancode which maps the keys by position on the keyboard and not by symbol.
See the SDL documentation: SDL2/CategoryKeyboard.

The solution is simple, it consists in replacing all SDL_Scancodes by SDL_Keycodes but...

⚠️ This change could have unwanted consequences for some users that might be difficult to predict.

This seems pretty critical to get fixed.
