OvmfPkg: remove gEfiLegacyBiosProtocolGuid
At this point, gEfiLegacyBiosProtocolGuid is unused; remove it.
This shrinks the list of resources scheduled for removal to:
- GUIDs (protocols or otherwise):
- SYSTEM_ROM_FILE_GUID (1547B4F3-3E8A-4FEF-81C8-328ED647AB1A)
- gEfiLegacy8259ProtocolGuid
- gEfiLegacyInterruptProtocolGuid
- headers:
- FrameworkDxe.h
- Protocol/Legacy8259.h
- Protocol/LegacyInterrupt.h

- The EFI Legacy BIOS Protocol is used to abstract legacy Option ROM usage
- under EFI and Legacy OS boot. This file also includes all the related
- COMPATIBILITY16 structures and definitions.
-
- Note: The names for EFI_IA32_REGISTER_SET elements were picked to follow
- well known naming conventions.
-
- Thunk is the code that switches from 32-bit protected environment into the 16-bit real-mode
- environment. Reverse thunk is the code that does the opposite.
