OvmfPkg: remove Csm/BiosThunk/VideoDxe

Browse Source 
Csm/BiosThunk/VideoDxe is not used by any platform at this point, remove
it.

This patch removes mentions of the following CSM resources from the source
code:

- GUIDs (protocols or otherwise):
  - gEfiLegacyBiosGuid
  - gEfiLegacyBiosProtocolGuid
  - gEfiVgaMiniPortProtocolGuid

- headers:
  - FrameworkDxe.h
  - Guid/LegacyBios.h
  - Protocol/LegacyBios.h
  - Protocol/VgaMiniPort.h

- PCDs:
  - PcdBiosVideoCheckVbeEnable
  - PcdBiosVideoCheckVgaEnable
  - PcdBiosVideoSetTextVgaModeEnable

which extends the list of resources scheduled for removal to:

- GUIDs (protocols or otherwise):
  - gEfiLegacyBiosGuid
  - gEfiLegacyBiosProtocolGuid
  - gEfiVgaMiniPortProtocolGuid

- headers:
  - FrameworkDxe.h
  - Guid/LegacyBios.h
  - Protocol/LegacyBios.h
  - Protocol/VgaMiniPort.h

- PCDs:
  - PcdBiosVideoCheckVbeEnable
  - PcdBiosVideoCheckVgaEnable
  - PcdBiosVideoSetTextVgaModeEnable
