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.
Sets the text display mode of the VGA controller to the mode specified by
ModeNumber. A ModeNumber of 0 is a request for an 80x25 text mode. A
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
is not functioning properly, then EFI_DEVICE_ERROR is returned. If the VGA
controller is successfully set to the mode number specified by ModeNumber, then
EFI_SUCCESS is returned.
@param[in] This A pointer to the EFI_VGA_MINI_PORT_PROTOCOL instance.
@param[in] ModeNumber The requested mode number. 0 for 80x25. 1 for 80x5.
@retval EFI_SUCCESS The mode number was set.
@retval EFI_UNSUPPORTED The mode number specified by ModeNumber is not supported.
@retval EFI_DEVICE_ERROR The device is not functioning properly.
