MAINTAINERS: add MM MISC section, add missing files to MISC and CORE

Add a MEMORY MANAGEMENT - MISC section to contain files that are not
described by other sections, moving all but the catch-all mm/ and
tools/mm/ from MEMORY MANAGEMENT to MEMORY MANAGEMENT - CORE and MEMORY
MANAGEMENT - MISC as appropriate.

In both sections add remaining missing files.  At this point, with the
other recent MAINTAINERS changes, this should now mean that every memory
management-related file has a section and assigned maintainers/reviewers.

Finally, we copy across the maintainers/reviewers from MEMORY MANAGEMENT -
CORE to MEMORY MANAGEMENT - MISC, as it seems the two are sufficiently
related for this to be sensible.
