[SWDEV-528647/SWDEV-528450] Reduce API load times and libdrm/libdrm_amdgpu dynamic loading (#333)

Changes:
- Removed libdrm/libdrm_amdgpu dependencies
- Added/updated new internal libdrm/libdrm_amdgpu/xf86drm APIs
  to allow our APIs to reference before dynamic loading
  the libdrm/libdrm_amdgpu libraries:
  1. amdgpu_drm.h to what's seen in mainline
  2. Added xf86drm.h to whats seen in mainline
- Modified internal DRM capabilities:
  1. Require each API to independently connect to libdrm/libdrm_amdgpu
     + validate API handles reponses accordingly
  2. Initialization of AMD SMI no longer has as strong of a tie to
     libdrm
- Updated internal implementations of several APIs which have
connections to libdrm/libdrm_amdgpu or APIs which have conflicts
with open libdrm/libdrm_amdgpu connections:
  1. amdsmi_init()
  2. amdsmi_get_gpu_vram_usage()
  3. amdsmi_get_gpu_asic_info()
  4. amdsmi_get_gpu_vram_info()
  5. amdsmi_get_gpu_vbios_info()
  6. amdsmi_get_gpu_driver_info()
  7. amdsmi_get_gpu_virtualization_mode()
  8. amdsmi_set_gpu_memory_partition()
  9. amdsmi_set_gpu_memory_partition_mode()
- Cleaned up effected tests/APIs
