OvmfPkg: remove Pcd8259LegacyModeEdgeLevel and Pcd8259LegacyModeMask

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

- Pcd8259LegacyModeEdgeLevel
- Pcd8259LegacyModeMask

This shrinks the list of resources scheduled for removal to nil.

-  ## Pcd8259LegacyModeMask defines the default mask value for platform. This

-  #  value is determined.

-  #  1) If platform only support pure UEFI, value should be set to 0xFFFF or

-  #     0xFFFE; Because only clock interrupt is allowed in legacy mode in pure

-  #     UEFI platform.

-  #  2) If platform install CSM and use thunk module:

-  #     a) If thunk call provided by CSM binary requires some legacy interrupt

-  #        support, the corresponding bit should be opened as 0.

-  #        For example, if keyboard interfaces provided CSM binary use legacy

-  #        keyboard interrupt in 8259 bit 1, then the value should be set to

-  #        0xFFFC.

-  #     b) If all thunk call provied by CSM binary do not require legacy

-  #        interrupt support, value should be set to 0xFFFF or 0xFFFE.

-  #

-  #  The default value of legacy mode mask could be changed by

-  #  EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely need change it

-  #  except some special cases such as when initializing the CSM binary, it

-  #  should be set to 0xFFFF to mask all legacy interrupt. Please restore the

-  #  original legacy mask value if changing is made for these special case.

-  ## Pcd8259LegacyModeEdgeLevel defines the default edge level for legacy

-  #  mode's interrrupt controller.

-  #  For the corresponding bits, 0 = Edge triggered and 1 = Level triggered.
