PrmPkg/Application/PrmInfo: Add initial application

Adds a new UEFI application called "PrmInfo" that allows a user
to display and test Platform Runtime Mechanism (PRM) modules.

Execute the application help command for detailed usage
instructions and examples of how to use the application:
  "PrmInfo -?"

This application is intended to be helpful during PRM enabling
by allowing the user to:

1. Confirm that their firmware port of the PRM infrastructure
   implemented in this package is functioning correctly.

2. Quickly get information about what PRM modules and handlers
   are present on a given system.

3. Quickly test PRM handlers without booting to a fully featured
   operating system.

4. Develop and exercise PRM handlers prior to the availability of
   an operating system that is PRM aware.

Adds a brief section to Readme.md about the PrmInfo UEFI application
with a link to allow the reader to find more information about the
application if interested.
