[Android] Adding alternate keyboard layout support

[Solanaar]

Currently, ArmorPaint on Android only seems to be using the standard US layout. As a German I use a standard QWERTZ keyboard layout which makes specific tasks very complicated, like changing keyboard shortcuts that require "+".

Suggestion:
Automatically check which keyboard layout is currently being used by the operating system.

• OR -

Add an option to select your keyboard layout in the settings.

ArmorPaint version:
Version 1.0 alpha

OS / GPU model:
Android 14
One UI 6.1.1
