gl-renderer: support XYUV8888 wl_shm format

Browse Source 
This support is added so that the XYUV shader variant can be tested with
wl_shm from the test suite.

Libwayland version requirement is bumped to get WL_SHM_FORMAT_XYUV8888.
Libwayland is bumped to 1.18 too in the CI image. libwayland-dev package
is dropped, because we build wayland anyway.
