The original sway output config implementation enabled one output at a
time, testing modes, render formats and VRR support as it went along.
While this sort of fallback is easy to do, it has the downside of not
considering the effect of neighbor outputs on the configuration
viability.
With backend-wide commits, we can now better consider the effect of
neighbor outputs, but to handle the fact that we commit all outputs at
once we need to perform a more elaborate search of viable
configurations.
Implement a recursive configuration search for when the primary
configuration failed to apply.
We want to check if a config_head existed for the current
matched_output_config, so we should check cfg->output. sway_output is a
temporary variable from a previous wl_list_for_each, and does not
contain anything useful to us.

Check if the app that requested a token has provided a valid input
serial and a focused surface. Downgrade activation request to urgency
otherwise.
This is mostly in line with what other Wayland compositors decided to
do, and offers a better security than the original logic.
We tried to synchronize layer shell popups with the parent layer shell
on commits, but this is subtly wrong because we would only update
the position for one layer shell that was committed, but not any other
layer that might be affected. By moving handling to the scene descriptor
we can iterate all popups and ensure they are synchronized.

Add a NULL check in `find_mapped_layer_by_client` like the one in `arrange_surface`.
Instead of doing this roundabout thing where we get the surface from the
view, let's instead get it from the `wlr_surface_state` that we already
track in `handle_commit`. This makes the NULL state impossible which is
what the old `get_geometry` is checking for and generally cleans
things up a little bit.
Also don't check if the geometry x/y changed, those will always
be 0 for xwayland.
Since output layout is destroyed when the wayland display is destroyed
we run into a destroy listener order problem: Either the display starts
destroying the outputs first, in which case we're good: The existing
handling will clean up. However, things go wrong if the display decides
to destroy the output layout first. In this case, sway will hold
invalid references to the output layout as part of each output so that
when it finally goes to destroy them, sway will dereference destroyed
output layout bits.
