PrmPkg: Add initial PrmSampleHardwareAccessModule

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

Adds a sample PRM module that demonstrates:
  1. How to write a PRM module
  2. How to use multiple PRM handlers in a module
  3. How to use a basic PRM OS service
  4. MSR access at OS runtime

Note: This module contains a PRM handler to read from the HPET MMIO
      range but the memory map changes needed for this to succeed
      are currently not implemented. These will be implemented in a
      future change.
