tearing-control-v1: implement

Implement the wp-tearing-control-v1 protocol allowing window to hint
the compositor that they prefer async "tearing" page flips.

Add tearing/no-tearing rules to allow the user to manually
enabled/disable tearing for a window.

Use async "tearing" page flips when a window that should be allowed to
tear is fullscreen.

This still requires several kernel patches to work with the wlroots
atomic DRM backend. For now, either set WLR_DRM_NO_ATOMIC=1 or use a
custom kernel that includes the unmerged patches (such as CachyOS).
