refactor(3p/exwm): Simplify and improve focus handling r/7106

- No need for two different timers, roll them into one.
- Debounce focus updates.
- Handle "no focus" frames.

Depot note: This patch was taken from Sibalien's fork of EXWM, and I'm
experimentally adding it here to see if it has any effect on wonkiness
around focusing.
