[Feature] Toggle touchscreen at different stylus levels

[zeroxoneafour]

Palm rejection was bugging out on my surface, so I whipped up this patch to make it better.

You can now configure the touch screen to turn off -

• When it detects the stylus at all (this is the old default)
• Only when it detects that the stylus is being hovered or is being used
• Only when the stylus is being used

The new config setting, Touchscreen.DisableOnStylusLevel, allows you to pick between the three options. By default, for compatibility, connected is picked. This is also the case if the option is not there or is invalid. I personally prefer active, and contact guarantees stability when writing.

I tested this on my Surface Pro 9 running Fedora 44 and it works. Idk why the CI runner for the Arch build failed.
