ShellPkg: make automatically created shells quit automatically

This creates a new parameter to this shell implementation “_exit” that causes the shell to automatically exit after running the initial specified command line.  This also automatically uses that command in the Execute() API.

ArmPkg/BdsLib: Fixed manipulation of the Memory Map returned by GetMemoryMap()

The UEFI specification mandates that software uses the DescriptorSize returned
by the GetMemoryMap() function to find the start of each EFI_MEMORY_DESCRIPTOR
in the MemoryMap array. This allows for future expansion of the EFI_MEMORY_DESCRIPTOR.

ArmPlatformPkg/ArmVExpressLibCTA15-A7: Mapped the extra 1GB of DRAM in the MMU

ARM Versatile Express TC2 Core Tile has two profiles: the 1GB DRAM core tile or
the 2GB DRAM core tile profiles.
By default UEFI assumes, it is the 1GB core tile. In case of 2GB DRAM it declares
this additional 1GB resource system memory to UEFI. But the previous code did
not map this memory in the MMU Page Table.
So, the memory was allocatable by UEFI modules, but was not accessible by the CPU
(because not mapped).

MdeModulePkg: Variable drivers robustly handle crashes during Reclaim().

PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid.
Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.
