minigbm: virtio-gpu: check format support when adding combinations

Updates the minigbm virtio backend to check for renderer support
before advertising support of various combinations. This prevents
minigbm from advertising yuv/nv12 formats which are not supported
on Cuttlefish when running on GCE with Nvidia GPUs which do not
support GBM.
