Subject: config: Force modeset before running deferred configs

Some commands require outputs to be enabled. These commands are deferred
to allow outputs to be discovered, but the delayed modeset might only
run some time later.

Force a modeset to occur before running deferred commands.

Fixes: https://github.com/swaywm/sway/issues/8433
(cherry picked from commit 6111297d91faf5f2820acaa14d76d6389b469b77)
