drm/i915/vgpu: improve vgpu abstractions

Browse Source 
Add intel_vgpu_register() abstraction, rename i915_detect_vgpu() to
intel_vgpu_detect() to match other function naming, un-inline
intel_vgpu_active(), intel_vgpu_has_full_ppgtt() and
intel_vgpu_has_huge_gtt() to reduce header interdependencies.

The i915_vgpu.[ch] filename and intel_vgpu_ prefix discrepancy remains.
