[feature] Support for Windows ARM

[alexiokay]

It would be so nice to be able to install this app natively on my surface pro with snapdragon cpu.

if someone needs it, I have built portable 0.6 version for ARM WIndows. This is my fork: https://github.com/alexiokay/infinipaint

Works well for me, the only issues are:

1. when I create text area and click inside it doesn't trigger the on-screen keyboard.
