OvmfPkg: remove LegacyBiosDxe PCDs 

The following PCDs are unused at this point; remove them:

- PcdEbdaReservedMemorySize
- PcdEndOpromShadowAddress
- PcdHighPmmMemorySize
- PcdLegacyBiosCacheLegacyRegion
- PcdLowPmmMemorySize
- PcdOpromReservedMemoryBase
- PcdOpromReservedMemorySize

This shrinks the list of resources scheduled for removal to:

- GUIDs (protocols or otherwise):
  - gEfiLegacy8259ProtocolGuid
  - gEfiLegacyBiosPlatformProtocolGuid
  - gEfiLegacyBiosProtocolGuid
  - gEfiLegacyInterruptProtocolGuid

- headers:
  - FrameworkDxe.h
  - Protocol/Legacy8259.h
  - Protocol/LegacyBios.h
  - Protocol/LegacyBiosPlatform.h
  - Protocol/LegacyInterrupt.h
