OvmfPkg: remove gEfiVgaMiniPortProtocolGuid

At this point, gEfiVgaMiniPortProtocolGuid is unused; remove it.

This shrinks the list of resources scheduled for removal to:

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

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

- PCDs:
  - PcdBiosVideoCheckVbeEnable
  - PcdBiosVideoCheckVgaEnable
  - PcdBiosVideoSetTextVgaModeEnable

-  Sets the text display mode of a VGA controller.

-  ModeNumber of 1 is a request for an 80x50 text mode.  If ModeNumber is greater

-  than MaxModeNumber, then EFI_UNSUPPORTED is returned.  If the VGA controller

-  controller is successfully set to the mode number specified by ModeNumber, then

-  EFI_SUCCESS is returned.
