Using a directory directory as input in a custom_target was deprecated and printed the message
"This will become a hard error in the future."
It did become a hard error now.

Make sure `layer_commit` passes on complete frames in `comp_gl_client.c`
even when EGL_ANDROID_native_fence_sync is not available.

The `insert_fence` function defined in `comp_egl_client.c` and passed as
argument to `comp_egl_client::client_gl_compositor_init` is only setting
up a proper fence when EGL_ANDROID_native_fence_sync is available,
resulting in a no-op otherwise.

However the fact that the insert_fence function is still valid results
in the `glFlush` workaround from
`comp_gl_client::client_gl_compositor_layer_commit` not kicking in.

To fix this define a NULL `insert_fence` function when
EGL_ANDROID_native_fence_sync is not available, and while at it turn the
`glFlush` workaround into a `glFinish` for extra safety.

This ensures that frames are always complete after
`client_gl_compositor_layer_commit` has been called.

When surface comes from client, it's not reuseable after
client exits. Removing the timeout so runtime can release all the
graphcis resources associated with surface.

Useful for setups that need some tuning to their sensors before sending
data to a SLAM system.
Removes the submit_frames property from wmr_camera as this replaces it.

Commit 749723f0 ("xrt: Remove xrt_view::display::{w|h}_meters")
accidentally removed some references to {w|h}_pixels as well as
{w|h}_meters. This resulted in recommended view image sizes of 0px*0px.

Revert those changes without reverting the rest of the commit.

Fixes: 749723f0 ("xrt: Remove xrt_view::display::{w|h}_meters")

This reverts commit b396c200.

The issue has been fixed in libsurvive [1]
