Introduce ARM and AArch64 instances of the CpuExceptionHandlerLib which provides exception handling and registration of handlers regardless of execution phase. Two variants of the ArmExceptionLib are provided: one where exception handlers reside within the module (meeting appropriate architectural alignment requirements for the vector table) and another one that will relocate a copy of thee xception handlers to an address specified by PcdCpuVectorBaseAddress. The ArmRelocateExceptionLib is intended for use in cases where ArmExceptionLib is too large for the application (uncompressed XIP images) as driven by the vector table alignment padding. The AArch64 build of this library supports execution at EL1, EL2, and EL3 exception levels. Tested on ARM, and AArch64 with SEC, DXE Core, and CpuDxe modules.
