StandaloneMmPkg/Core: fix bogus FV pointer in DEBUG string
FvIsBeingProcessed () emits a DEBUG print with the intent to print
the memory address of the FV that is being processed, but instead,
it prints the contents of an uninitialized stack variable.

StandaloneMmPkg: generate position independent code for StMM core
The standalone MM core runs in a restricted environment that is set
up by a higher privilege level, and which may not allow memory regions
to be writable and executable at the same time.
This means that making the StMM core self-relocatable requires that
all the targets of the relocation fixups are outside of the executable
region of the image, given that we cannot remap the executable code
writable from the executable code itself without losing those execute
permissions.
So instead, use the existing toolchain support to ensure that position
independent code is used where possible, and that all the remaining
relocated quantities are emitted into the data section. (Note that
staticallly initialized const pointers will be emitted into the
.data.rel.ro section, which gets pulled into the .data section by
our linker script)
To ensure that we don't pick up any absolute references in executable
code inadvertently (e.g., in assembler code), add the '-z text' linker
option which will force the build to fail in this case.

StandaloneMmPkg/StandaloneMmCoreEntryPoint: relocate StMM core on the fly
Apply PE/COFF fixups when starting up the standalone MM core, so that
it can execute at any address regardless of the link time address.
Note that this requires the PE/COFF image to be emitted with its
relocation section preserved. Special care is taken to ensure that
TE images are dealt with correctly as well.
