anv/queue: Allow temporary import of SYNC_FD semaphores

We didn't allow them before because it didn't look like the spec allowed
it.  It certainly doesn't make much sense.  However, there are CTS tests
that apparently hit this.  What the spec actually says is:

    "Importing a payload using handle types with copy transference
    creates a duplicate copy of the payload at the time of import, but
    makes no further reference to it. Fence signaling, waiting, and
    resetting operations performed on the target of copy imports must
    not affect any other fence or payload."

A SYNC_FD has copy transference but the import may be temporary or
permanent.  If you do a permanent import of something with copy
transference, I guess it's supposed to work and end up resetting the
permanent state.  In any case, there seems to be no real harm in
allowing it, so why not.

Revert "egl/android: add missing include"

This reverts commit 688d866eca8943f09cd846ffb045e18f6ec0677c.

The include I added in 688d866eca isn't actually useful, as it only
declares the opaque struct ANativeWindow.
However, this caused build issues for android-x86 [1] due to the header
being moved in Android O.

egl/wayland: Use roundtrips when awaiting buffer release

In get_back_bo, we use wl_display_dispatch_queue() to block and wait for
a buffer release event. However, not all Wayland compositors flush the
client socket on posting a buffer-release event, so by only blocking
client-side, we may block indefinitely, or at least need to wait for an
input event / frame completion to arrive for the compositor to flush.

We now use dispatch_queue as a first pass, but if our entire buffer pool
is exhausted, use a roundtrip (an immediately-triggered wl_callback) to
ensure that the compositor flushes out our release event immediately.

The only change in VGPR spills is the elimination of all spills
in Tomb Raider at Ultra settings. Closer examination shows that
the shaders go over the limit because they contain three
expressions a mul, rcp and ubo load. The ubo load is actually
used elsewhere and is therefore stored in a temp already in IR
such as tgsi but glsl ir counts it agaist the if cost.
