StandaloneMmPkg/Core: Remove unneeded check
Remove unneeded check MmIsBufferOutsideMmValid() when
StandaloneMmCore checks if the BS data memory described
by a memory allocation HOB needs to be migrated to Mmram.
Currently, the API MmIsBufferOutsideMmValid() return TRUE
when input memory range belongs to non-Mmram memory. Now
the API will be changed in following 5 commits to return
TRUE when a memory range belongs to non-Mmram memroy and
the memory is inside a range described by resource HOB.
This may cause PF when some SMI handler access the memory
from a memory allocation HOB that is not migrated.
To solve this issue, we can directly remove the check
MmIsBufferOutsideMmValid() and always migrate the BS data
memory described by a memory allocation HOB to Mmram.

StandaloneMmPkg/MemLib: Check if the non-MMRAM buffer is valid
Check if the non-MMRAM buffer is inside valid non-mmram
range in API MmIsBufferOutsideMmValid of StandaloneMmMemLib.
Previously, the API only checks if the input buffer is
overlapped with MMRAM range. Currently, in the new standalone
MM infrastructure, we limit the non-MMRAM access to the ranges
reported by the resource HOB. To meet the new design, in this
API, we cache all the memory ranges reported by the resource
HOB and check if the input buffer is inside valid non-MMRAM
ranges reported by the resource HOB.

StandaloneMmPkg/Core: Check Resource HOB and Mmram ranges
Check if the all the resource HOB in the input HOB list of
MmCore entry only covers non-Mmram ranges. The Resource HOB
is to describe the accessible non-Mmram range. All Resource
HOB should not overlap with any Mmram range.

StandaloneMmPkg/MemLib: remove unnecessary check
Remove unnecessary check in API MmIsBufferOutsideMmValid of
StandaloneMmMemLib.
The API is used to check if a input buffer is outside MMRAM and
inside a valid non-MMRAM range. Previously, the API only checks
if the input buffer is
overlapped with MMRAM range. In the last
commit, we add logic to check if the input buffer is inside valid
non-MMRAM
ranges reported by the resource HOB. Since the resource
HOB only covers valid non-MMRAM ranges, we doesn't need to check
if the input buffer is inside the MMRAM anymore.
