subtree(3p/exwm): update & hard reset to commit 'a6e66f5e33' r/7478

This contains a bunch of upstream changes after the new maintainers of
EXWM took over, including proper mainlined versions of patches I've
been carrying around here manually.

Notably this undoes the Chromium focus fix patch, lets see how that goes.
