The DXE and SMM MAT logic will now invoke the DumpImageRecords() on DEBUG builds at the EndOfDxe event to install the MAT. v2: - A one-line change in patch 3 was moved to patch 9 for correctness. Reference: https://github.com/tianocore/edk2/pull/4590 Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=4492 The UEFI and SMM MAT logic contains duplicate logic for manipulating image properties records which is used to track runtime images. This patch series adds a new library, ImagePropertiesRecordLib, which consolidates this logic and fixes the bugs which currently exist in the MAT logic. The first patch adds the ImagePropertiesRecordLib implementation which is a copy of the UEFI MAT logic with minor modifications to remove the reliance on globabl variables and make the code unit testable. The second patch adds a unit test for the ImagePropertiesRecordLib. The logic tests various potential layouts of the EFI memory map and runtime images. 3/4 of these tests will fail which demonstrates the MAT logic bugs. The third patch fixes the logic in the ImagePropertiesRecordLib so that all of the unit tests pass and the MAT logic can be fixed by using the library. The remaining patches add library instances to DSC files and remove the image properties record logic from the SMM and UEFI MAT logic.
