PrmPkg: Add initial PrmSampleMemoryAllocationModule

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3812

DEPRECATED: This module is no longer relevant since OS Services that
allow memory allocation have been removed. It is still present in the
source tree in the event dynamic memory allocation at OS runtime is
needed again.

  Adds a sample PRM module that demonstrates:
  1. How to write a PRM module
  2. How to use a basic PRM OS service
  3. How to dynamically allocate memory at OS runtime
