transaction: Only wait for ack from visible views

Browse source 
Transactions currently wait for all configures to be acked, regardless
fo what they were sent to. This includes views that are hidden in tabbed
or stacked containers. If these views do not ack the configure in
response to a single frame callback, they can cause transaction
timeouts.

Check if a container is hidden before registering the configure serial
and saving any view buffers.

Closes: https://github.com/swaywm/sway/issues/6023
