StandaloneMmPkg: StandaloneMmIplPei: Prevent Freeing Zero Pages
There could be scenarios where the HOB producer does not create any HOBs.
In such cases, the buffer intended to be freed will have zero pages.
This update addresses the issue that could cause assertions during
runtime by ensuring that buffers with zero pages are not freed.

StandaloneMmPkg: StandaloneMmIplPei: Use MM access to open the regions
Current MM IPL in PEI phase does not open the MMRAM regions through MM
access PPI. This is causing some platforms like OVMF reading all `0xFF`s
when trying to relocate the Standalone MM core.
This change opens all the MMRAM regions provided by MM access PPI and
closes + locks the regions after initial MM foundation setup, when MM
Access PPI is available.
Platforms that require MM access PPI can inject depex through libraries.

OvmfPkg: SmmCpuFeaturesLib: Abstract out SMM specific implementations
This update refactors the existing SmmCpuFeaturesLib to eliminate direct
calls to SMM-specific functions.
In particular, the constructor has been relocated to traditional MM-
specific C files, utilizing a common entry point.
Furthermore, several implementation-specific functions have been
modularized into its respective C files.
These changes lay the groundwork for supporting a Standalone MM-based
solution in the future.
