- Backport perinputconfig from main-tracking to v0.5
- It's actually simpler since v0.5 already has the keyboard groups as a
list as opposed to what's in current main
- Array replaced singular variables for configuration
- Pointer: Only applies to enable-state, acceleration profile, and speed
- Keyboard: Basically xkb_rule_names plus name
- Like EX: Rules, requires NULL/default set at the end
