[efi] Include EFI_CONSOLE_CONTROL_PROTOCOL header
The EFI_CONSOLE_CONTROL_PROTOCOL does not exist in the current UEFI
specification, but is required to enable text output on some older EFI
1.10 implementations (observed on an old iMac).
The header is not present in any of the standard include directories,
but can still be found in the EDK2 codebase as part of
EdkCompatibilityPkg.
