GPU: define traits for maximum display heads

Browse Source 
Some virtual GPUs support specific maximum display heads (or called as
display outputs). This commit is to define traits for display heads, so
that it's able to associate the supported maximum display heads to vGPU
resource providers and it can schedule resource providers based on the
allowed maximum number of display heads.
