The InterruptId has a different width for GicV2 and GicV3 (respectively
10bit and 24bit).
The function prototype has been changed to return this value to make the
caller GIC architecture version independent. Otherwise, we would have need
to expose a different mask to allow the caller to retrieve this value from
the read register.

Checking if a core if the primary/boot core used to be done with the macro
IS_PRIMARY_CORE().
Some platforms exposes configuration registers to change the primary core.
Replacing the macro IS_PRIMARY_CORE() by ArmPlatformIsPrimaryCore() allows
some flexibility in the way to check the primary core.

Since the System Memory initialization has been moved inside ArmPlatformSecLib
on some platforms, the use of this library could crash if the firmware engineer
forgot to initialize the DRAM.
This library 'patches' the DRAM to add an infinite loop.

The function 'ArmGicAcknowledgeSgiFrom' was actually acknowledging Interrupts (and not only SGIs).
ArmPkg/ArmGicLib: Introduced the PCD PcdGicPrimaryCoreId
This PCD defines the Id of the primary core in the GIC.

The denomination 'Normal' was used to make reference to the 'Normal'
or 'Non Secure' or 'Non Trusted' world.
To avoid confusion, this prefix has been removed from PCDs to define
the normal world.
The PCDs explicitely related to the Secure/Trusted World continue to
have the 'Sec' prefix.

On MpCore system, the primary core can now be any core of the system.
To identify the primary core, you can use 'gArmTokenSpaceGuid.PcdArmPrimaryCoreMask'
and 'gArmTokenSpaceGuid.PcdArmPrimaryCore'.
These PCDs by default use the ClusterId and CoreId to identify the core. And the
primary core is defined as the ClusetrId=0 and CoreId=0.
The helper macros are: IS_PRIMARY_CORE(MpId), GET_CORE_ID(MpId), GET_CLUSTER_ID(MpId),
GET_CORE_POS(MpId), PRIMARY_CORE_ID.

This library is the interface for the ARM Generic Interrupt Controller
Architecture Specification.
ARM Platform can use any GIC controller (not necessary PL390 GIC).

The PcdStandalone is a PCD ARM Ltd uses to make the difference between a standalone UEFI (boot
from cold boot to Boot Manager without user intervention) and a Debug UEFI firmware (the firmware
engineer has to copy the Normale World image into the DRAM to enable his/her firmware).
By coping the firmware into DRAM in the non standalone version it is much faster than reflashing
the NOR Flash after each build.
ArmPlatformSecExtraAction() function is called just before the Sec module jump to normal world.
The platform firmware can run extra actions at this stage.
The 'ARM Standalone' concept has moved to the implementation of ArmPlatformSecExtraAction() for
the ARM development boards (in ArmPlatformPkg/Library/DebugSecExtraActionLib).
