protocols: add Fifo-v1 and commit-timing-v1 (#12052)

* protocols: add Fifo-v1

introduce fifo-v1

* fifo: only present locked surfaces

dont present to unlocked surfaces and commit pending states from the
fifo protocol.

* fifo: cformat

cformat

* protocols: add committiming and surface state queue

introduce CSurfaceStateQueue and commit-timing-v1

* fifo: schedule a frame if waiting on barrier

if we are waiting on a barrier the state doesnt commit until the next
refresh cycle meaning the monitor might have no pending damage and we
never get onPresented to unlock the barrier, moment 22. so schedule a
frame.

* fifo: properly check monitor intersection

check for m_enteredoutputs or monitor intersection if client hasnt bound
one yet, and dont fifo lock it until the surface is mapped.

* buffer: try to merge states before committing them

try to merge states before committing them meaning way less churn and
surface commits if a surface sends multiple small ones while we wait for
buffer readyness from either fifo locks or simply fences.

* buffer: dont commit states past the buffer

certain changes are relative to the buffer attached, cant go beyond it
and apply those onto the next buffer.

* buffer: set the lockmask directly

cant use .lock since the state hasnt been queued yet, set the lockmask
directly when exporting buffer fence.

* fifo: dont fifo lock on tearing

dont fifo lock on tearing.

* buffer: queue the state directly

queue the state directly and use the .lock function instead of directly
modify the lockMask on the state.

* buffer: revert creating texture at commit time

fifo barriers introduces such long wait that upon commit time a
race happends with current xdg configure implentation that the buffer
and image is actually destroyed when entering commitState, doing it at
buffer creation time with EGL_PRESERVED_KHR means it sticks around until
we are done. so revert 82759d4 and 32f3233 for now.

* buffer: rename enum and lockreasons

eLockReason and LOCK_REASON_NONE.

* fifo: workaround direct scanout lock

workaround cursor commits causing fifo to get forever locked, this
entire thing needs to be worked out.
