ArmPkg/ArmGic: Drop GICv2 legacy support
Support for GICv2 legacy mode was introduced to accommodate secure world
firmware that was lagging behind in terms of development, and was
running the GIC in v2 mode on the secure side for lack of a GICv3
driver.
As per the GIC architecture, the non-secure world can only run the GIC
in v3 mode if the secure world does so too.
At this point, there is no longer a need to for this fallback: GICv2
support it still needed for platforms such as Raspberry Pi 4 that do not
implement GICv3 at all. But on platforms that do implement it, falling
back to GICv2 is unnecessary.

ArmPkg/ArmGic: drop ArmGicEnableInterruptInterface from ArmGicLib
The ArmGicLib API exposes ArmGicEnableInterruptInterface () and
ArmGicDisableInterruptInterface (), but only the former is actually
used, and only from the GICv2 driver. So drop the API entirely, and
invoke the v2 version of the underlying interface directly.

ArmPkg/ArmGic: Disentangle v2 and v3 versions of IRQ en/disable APIs
ArmGicLib is agnostic about the difference between v2 and v3, but its
APIs are only called from code that is either v2-specific or
v3-specific. That makes the generic interface kind of pointless, and we
can just merge this code into the callers.

ArmPkg/ArmGic: Move GICv3 sysreg check into ArmGicDxe
ArmGicArchLib implements a check on the accessibility of the GIC system
register interface, which is a prerequisite for using the GIC in v3
mode. It might be possible to use GICv2 compatibility mode on poorly
configured platforms where the GIC is v3 capable but not accessible, but
in most cases, the GIC is driven in its native mode.
This check is now only carried out in a single place, and there is not
really any reason to keep this in a separate library. Even though
ArmVirtPkg implements its own version, the basic check (and enablement
of the sysreg interface) is still needed.
So move this check into the DXE driver itself, and drop the dependency
on ArmGicArchLib. This allows it to be retired in a subsequent patch.
