PrmPkg/Test/UnitTest/Library: Add initial UEFI Boot Services test lib
Adds a host-based specific implementation of UefiBootServicesTableLib.
This library implements relatively simple versions of the functionality
in the actual boot services implementation and does not depend on
dynamic linking to the boot services table.
Most unit tests can install the dependencies their code under test
depends on prior to invocation and uninstall those dependencies after
the test to test code that directly depends on boot services.
