cursor-renderer-native: Support HW cursors on multiple GPUs

Browse Source 
On hybrid GPU systems, hardware cursors needs to be realized on all the
GPUs, as scanout cursor planes cannot be shared. Do this by moving gbm
buffer and drm buffer ID management to a per GPU struct, realizing a
cursor on each GPU when previously only realized on the primary GPU.
