PrmPkg: Add package and include headers

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

Adds a new package to maintain Platform Runtime Mechanism (PRM)
support.

This package is intended to include generic code that provides a
common infrastructure to support PRM in firmware and a collection
of sample PRM modules that demonstrate how to use the interfaces
and other package resources to author a PRM module.

The following initial headers are included in this commit:

* Prm.h - Includes common content for PRM with no dependencies on
  other PRM header files.

* PrmContextBuffer.h - Includes definitions for PRM context buffers.

  Context buffers are standardized structures that point to various
  resources available to a PRM handler during its execution.

* PrmDataBuffer.h - Includes definitions for PRM data buffers.

  Within the context of PRM, these data buffers are composed of a
  generic header followed by a variable length blob of arbitrary
  data.

* PrmExportDescriptor.h - Includes definitions for  creating PRM
  export descriptors.

  A PRM export descriptor is a structure referenced in the export
  table of PRM module that contains PRM-specific metadata about the
  module.

* PrmMmio.h - Includes definitions for describing MMIO ranges uses
  by PRM modules.

* PrmModule.h - Includes definitions commonly used by PRM module
  authors.

  This file is provided to serve as a convenient include for PRM
  module authors.

* PrmOsServices.h - Includes content specific to PRM OS services.

  OS Services will not planned to be present in the final version
  of PRM. The OS Services have been reduced to a simple debug print
  function. So this is currently planned to be a temporary file to
  support debugging during PRM development.

Note: Modules built for the UEFI environment can be built by Visual
      Studio and non-Visual Studio toolchains. However, PRM modules
      are currently only supported on Visual Studio toolchain due to
      usage of export tables.
