OvmfPkg/8259InterruptControllerDxe: Update to make it build for OVMF

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1496

Several updates have been made to the
OvmfPkg/8259InterruptControllerDxe driver to make it build under OvmfPkg:

A) Update the driver INF file to consume PCDs defined within OvmfPkg;
B) Remove the unnecessary dependency on the IntelFrameworkPkg header file
   'FrameworkDxe.h';
C) Remove the IntelFrameworkPkg & PcAtChipsetPkg DEC files dependency in
   the driver INF file.

A new GUID has been updated for the INF file.

Corresponding changes have been made in OVMF DSC files as well in order to
verify the build.

Please note that a subsequent commit (final patch of the series) will:

A) Add OvmfPkg/8259InterruptControllerDxe driver in OVMF FDF files;
B) Remove the consumption of PcAtChipsetPkg/8259InterruptControllerDxe
   driver in OVMF DSC/FDF files;
C) Remove the consumption of
   gPcAtChipsetPkgTokenSpaceGuid.Pcd8259LegacyModeEdgeLevel in OVMF DSC
   files.
