According to the discussion in "StandaloneMmPkg: Fix HOB space and
heap space conflicted issue" [1], Standalone MM modules should be HOB
consumers where HOB is read-only. Therefore, this patch removes the
supported functions for HOB creation in the StandaloneMmHobLib.

StandaloneMm has its own version of the ArmMmuLib library class, but
includes the ArmMmuLib header. This happens to work because the
prototypes that are referenced are the same, but this will no longer be
the case after a future patch. So correct the #includes.

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.

In a system implementing the variable store in MM, there are no variable
arch protocol and variable write arch protocol installed into the
DXE_SMM protocol database. On such systems, it is not required to
locate these protocols by the DXE runtime variable drivers because
it can be assumed that these protocols are already installed in the
MM context. But then such an implementation will deviate from the
existing traditional MM based variable driver implementation.
So in order to maintain consistency with the traditional MM variable
driver implementation, allow platforms to install these protocols into
the DXE protocol database but these protocol will not be consumed
by non-secure variable service runtime driver.
The Platform which uses StandaloneMM based secure variable storage
have to include this library

The Standalone MM environment runs in S-EL0 in AArch64 on ARM Standard
Platforms and is initialised during the SEC phase. ARM Trusted firmware
in EL3 is responsible for initialising the architectural context for
S-EL0 and loading the Standalone MM image. The memory allocated to this
image is marked as RO+X. Heap memory is marked as RW+XN.
Certain actions have to be completed prior to executing the generic code
in the Standalone MM Core module. These are:
1. Memory permission attributes for each section of the Standalone MM
Core module need to be changed prior to accessing any RW data.
2. A Hob list has to be created with information that allows the MM
environment to initialise and dispatch drivers.
Furthermore, this module is responsible for handing over runtime MM
events to the Standalone MM CPU driver and returning control to ARM
Trusted Firmware upon event completion. Hence it needs to know the CPU
driver entry point.
This patch implements an entry point module that ARM Trusted Firmware
jumps to in S-EL0. It then performs the above actions before calling the
Standalone MM Foundation entry point and handling subsequent MM events.
