ArmVirtPkg: Create platform DXE driver to detect the GIC version
Take the code from ArmVirtGicArchLib, which is injected into the unified
GIC driver by NULL library class resolution to set the associated PCDs
as the driver loads, and implement a DXE driver that performs the same
DT based detection.
However, in this case, the driver installs a NULL protocol under a GUID
that indicates the presence of either a V2 or a V3 (or later) GIC, in a
way that allows the DXE driver dispatcher to take this into account.
This will allow the unified GIC driver to be replaced with the split V2
and V3 versions, which is all we care to support going forward.

ArmVirtPkg: Implement stub DEPEX libraries for GIC v2/v3 presence
Allow the unified ArmGicDxe driver to be replaced with either the v2 or
the v3 one, depending on what the platform actually implements.
This involves injecting a DEPEX on the ArmVirtPkg specific GUID that
conveys whether the GIC is a revision 2 or a newer one.
This DEPEX injection is done by adding a NULL library class resolution
to each driver when incorporating it into the platform build. So add a
library for GICv2 and one for GICv3 or newer.

ArmVirtPkg: Switch all platforms to split v2/v3 GIC drivers
Use the separate v2 and v3 versions of the GIC driver, rather than the
unified one, which is a bit odd because a platform never implements
both, and GICv2 is obsolete by now.
The only reason the unified driver is being kept alive is for virtual
platforms that could decide to expose either. Let's refactor this a bit
so that the version detection is separated from the driver dispatch
itself, so that ordinary DEPEX resolution can be used to load either the
v2 or the v3 driver.

ArmVirtPkg: Retire the ArmVirtGicArchLib library
This library is no longer used so it can be removed.
