This patch adds a library that enables invocation of SVCs from Exception
Level EL0. It will be used by the Standalone MM environment to request
services from a software running in a privileged EL e.g. ARM Trusted
Firmware. The library is derived directly from Arm SMC Library.

Process any capsule HOBs that were left for us by CapsulePei. This
involves calling ProcessCapsules() twice, as explained in the comment
in DxeCapsuleLibFmp [sic].
1) The first call must be before EndOfDxe. The system capsules is processed.
If device capsule FMP protocols are exposted at this time and device FMP
capsule has zero EmbeddedDriverCount, the device capsules are processed.
Each individual capsule result is recorded in capsule record variable.
System may reset in this function, if reset is required by capsule and
all capsules are processed.
If not all capsules are processed, reset will be defered to second call.
2) The second call must be after EndOfDxe and after ConnectAll, so that all
device capsule FMP protocols are exposed.
The system capsules are skipped. If the device capsules are NOT processed
in first call, they are processed here.
Each individual capsule result is recorded in capsule record variable.
System may reset in this function, if reset is required by capsule
processed in first call and second call.

Now that ArmDmaLib can take care of its own memory allocation needs,
let's get rid of UncachedMemoryAllocationLib entirely. This forces
platforms to declare the required semantics (non-cache coherent DMA,
whichever way it is implemented), rather than using uncached memory
allocations directly, which may not always be the right choice, and
prevents sharing of drivers between platforms if one is cache coherent
and the other is not.

The debug implementation of the UncachedMemoryAllocationLib library
class relies on the creation of an uncached alias of a memory range,
while keeping the original cached mapping, but with read-only attributes
to trap inadvertent write accesses.
This is not a terribly good idea, given that the ARM architecture does
not allow mismatched attributes, and so creating them deliberately is
not something we should encourage by doing it in reference code.
So remove the library, and replace all references to it with a reference
to the non-debug version (unless the platform does not require a resolution
for it in the first place, in which case all UncachedMemoryAllocationLib
references can be removed altogether).

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.

The current implementation of ArmGicGetSupportedArchRevision ()
that is used by all ARM platforms is entirely stateless (in order
to support being executed from flash) so it needs to interrogate
the hardware for the supported GIC revision upon each invocation.
However, this statelessness is only needed for SEC type modules;
in all other cases, we could easily determine the GIC revision once,
and store the result in a global variable.
In preparation of having separate early and normal versions, this patch
introduces the ArmGicArchLib library class and default implementation,
and moves the existing ArmGicGetSupportedArchRevision () into it.
