Taylor Beebe 0a9e215312 MdeModulePkg: Add ImagePropertiesRecordLib Host-Based Unit Test 
Create a host-based unit test for the ImagePropertiesRecordLib
SplitTable() logic. This test has 4 cases which tests different
potential image and memory map layouts. 3/4 of these tests fail
with the logic in its current state to provide proof of the bugs
in the current MAT logic.
