MdePkg/IndustryStandard/ArmFfaSvc.h: add partition type helper
According to the FF-A specification, bit 15 of the partition ID
indicates the partition type:
- Bit[15] == 0: Identifies a Virtual Machine (VM), used by the Hypervisor.
- Bit[15] == 1: Identifies a Secure Partition, used by the SPM.
In other words, if bit 15 of the partition ID is set to 1,
it represents a Secure Partition; if it is 0,
it represents a Normal World partition.
Based on this spec, add helper to check partition id is secure partition
or not.

ArmPkg/Library/StandaloneMmEntryPoint: introduce IsSecureMmCommBufferAddr()
To verify whether MM communication uses a secure buffer,
introduce the IsSecureMmCommBufferAddr() function.
This is a preparatory patch for MM context generation on Arm.

ArmPkg/Library: add ArmMmHandlerContext for MM handler context management
Introduce ArmMmHandlerContext.h, which defines the ARM_MM_HANDLER_CONTEXT
structure passed to each MmHandler’s Context argument. This structure
provides:
- The current communication protocol type
- The service type
- Protocol-specific details
This enables MM drivers to differentiate requests from MM communication
versus DIRECT_MSG_REQ2, support both SPM_MM and FF-A v1.2, and determine
whether a request originated from the secure world.

ArmPkg/Include/IndustryStandard: introduce firmware update feature headers
The Platform Security Firmware Update specification, 1.0 for A-profile
(https://developer.arm.com/documentation/den0118/latest) describes
a standard mechanism for performing firmware updates on Arm platform.
This mechanism utilises the Arm Firmware Framework for Arm A-profile
specification to transfer the firmware update binaries
from the Normal World to the Secure World.
An update agent on the Secure world then updates the flash area with the new
update image.
Add related headers for firmware update feature.

ArmPkg/Library: introduce FmpDeviceLib using Firmware update ABI
FmpDeviceLib is platform specific library which is used to update
firmware using CapsuleUpdate framework via FmpDevicePkg in edk2.
According to Platform Security Firmware Update for A-profile:
https://developer.arm.com/documentation/den0118/latest,
FmpPsaFwuLib is implementation of FmpDeviceLib using PsaFwuLib
implementing firmware update ABI.
Here is brief view how it works
