RFR: 8347730: Replace SIZE_FORMAT in g1 [v2]

[Coleen Phillimore]

> Please review this change to replace SIZE_FORMAT with %zu in the g1 directory.  Most edits were by script but SIZE_FORMAT_W(n) was done sort of by hand.  Also fixed one place where preexisting formatting was bad.
> 
> Tested all the GC changes together (other PRs coming) with tier1-4 on x86 and aarch64.
