RFR: 8347924: Replace SIZE_FORMAT in memory and metaspace

[Coleen Phillimore]

Please review this change to replace SIZE_FORMAT with %zu in the memory and metaspace directories.  This code prints a lot of numbers so splitting this out.  Most done by script but a couple of hand-edited commits.
Testing with tier1-4.
