MdeModulePkg: Define memory attribute PPI
Define a PPI interface that may be used by the PEI core or other PEIMs
to manage permissions on memory ranges. This is primarily intended for
restricting permissions to what is actually needed for correct execution
by the code in question, and for limiting the use of memory mappings
that are both writable and executable at the same time.
