Backspace on Colemak keyboard layout doesn't work on Windows

[Susko3]

On the Colemak keyboard layout, the usual Caps Lock key is mapped to Backspace. This remapping works on linux/wayland, but doesn't on windows (the keycode reports as SDLK_CAPSLOCK even though it should be SDLK_BACKSPACE).

The root cause of this is probably the following code, disallowing caps lock remapping:

SDL/src/video/windows/SDL_windowskeyboard.c

Lines 132 to 136 in 70e43c1

	/* If this key is one of the non-mappable keys, ignore it */
	/* Uncomment the second part re-enable the behavior of not mapping the "`"(grave) key to the users actual keyboard layout */
	if ((keymap[scancode] & SDLK_SCANCODE_MASK) /*|| scancode == SDL_SCANCODE_GRAVE*/) {
	continue;
	}

Fixed, thanks!
