[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

Device: Samsung Tab S8
