platform/x86/intel/ifs: Add metadata validation
The data portion of a IFS test image file contains a metadata region
containing possibly multiple metadata structures in addition to test
data and hashes.

| META_TYPE_END (=0) |
+----------------------+ meta_size + 4

+----------------------+ meta_size + 8
Introduce the layout of this meta_data structure and validate
the sanity of certain fields of the new image before loading.
Tweak references to IFS test image chunks to reflect the updated
layout of the test image.
