This commit makes the behavior for PeiGetVariable() match the following
specification-defined behavior. It is now consistent with the DXE/SMM
variable driver implementation.
The UEFI specification v2.8 Errata A Section 8.2 "GetVariable()"
"Attributes" parameter description states:
"If not NULL, a pointer to the memory location to return the
attributes bitmask for the variable. See 'Related Definitions.'
If not NULL, then Attributes is set on output both when
EFI_SUCCESS and when EFI_BUFFER_TOO_SMALL is returned."
The attributes were previously only returned from the implementation
in Variable.c on EFI_SUCCESS. They are now returned on EFI_SUCCESS or
EFI_BUFFER_TOO_SMALL according to spec.

From the function description of GetIfrBinaryData(), FormSetGuid can be
NULL. However, FormSetGuid is passed to IsZeroGuid(). This causes exception
when FormSetGuid is NULL.

SdMmcPciHcDxe driver used to read response only after
command and data transfer completed. According to SDHCI
specification response data is ready after the command
complete status is set by the host controller. Getting
the response data early will help debugging the cases
when command completed but data transfer timed out.

To allow for easier debug of failing commands we
have added a capability to print TRB and command
packet when we start execution of the TRB(on
DEBUG_VERBOSE level) and when the TRB failed to
execute correctly(on DEBUG_ERROR level). Additionally
we will also print error interrupt status and interrupt
status register on failed SD command.

EDK2's implementation of the LoadImage() boot service permits non-native
binaries to be loaded (i.e., X64 images on IA32 firmware), but any
attempts to start such an image using StartImage() will return
EFI_UNSUPPORTED.
The integration of the PE/COFF emulator protocol into the DXE core
deviates slightly from this paradigm, given that its IsImageSupported
hook as well as its RegisterImage hook are invoked from LoadImage,
and by the time StartImage is called, no opportunity is given to the
provider of the PE/COFF emulator protocol to prevent an image from
being started if it only supports loading it.
To address this disparity, let's move the invocation of RegisterImage()
to the implementation of the StartImage() boot service, allowing the
emulator to permit LoadImage() but reject StartImage() on images that
turn out not to meet the requirements of the emulator as it is being
started.

The commit will avoid unmapping the same resource in error handling logic
for function BuildAdmaDescTable() and SdMmcCreateTrb().
For the error handling in BuildAdmaDescTable():
The error is directly related with the corresponding Map() operation
(mapped address beyond 4G, which is not supported in ADMA), so the Unmap()
operation is done in the error handling logic, and then setting
'Trb->AdmaMap' to NULL to avoid double Unmap.
For the error handling in SdMmcCreateTrb():
The error is not directly related with the corresponding Map() operation,
so the commit will update the code to left SdMmcFreeTrb() for the Unmap
operation to avoid double Unmap.

Current UpdateCapsule service will reject all non-reset capsule images and
return EFI_OUT_OF_RESOURCE if the system is at runtime. This will block a
platform CapsuleLib from implementing ProcessCapsuleImage() with runtime
capsule processing capability.
This patch removes this restriction. The change is controled by a feature
PCD PcdSupportProcessCapsuleAtRuntime, and the default value is FALSE
which means not enable this feature.

This commit fixes an offset calculation that is used to write the
VarErrorFlag UEFI variable to the UEFI variable runtime cache.
Currently a physical address is used instead of an offset. This
commit changes the offset to zero with a length of the entire
non-volatile variable store so the entire non-volatile variable
store buffer in SMRAM (with the variable update modification) is
copied to the runtime variable cache. This follows the same pattern
used in other SynchronizeRuntimeVariableCache () calls for
consistency.
* Observable symptom: An exception in SMM will most likely occur
due to the invalid memory reference when the VarErrorFlag variable
is written. The variable is most commonly written when the UEFI
variable store is full.
* The issue only occurs when the variable runtime cache is enabled
by the following PCD being set to TRUE:
gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
