remoting: Use DRM FourCC formats instead of GBM formats
The remoting plugin currently has a set_gbm_format() hook, which accepts GBM_FORMAT_* tokens from the host to set as a supported format. GBM_FORMAT_* values are strictly aliased with DRM_FORMAT_*.
In order to avoid an extra unnecessary dependency from the remoting plugin on GBM, switch to using the formats from libdrm instead.
This fixes a compile error seen when the remoting plugin is enabled:
../remoting/remoting-plugin.c:39:10: fatal error: gbm.h: No such file or directory 39 | #include <gbm.h> | ^~~~~~~ compilation terminated.
