Emilio Cobos Álvarez d1a9b44ea6 Bug 1560188 - Fix and improve display list memory reporting. r=mattwoodrow,njn
I missed in bug 1487216 that the pres arena memory reporting assumes that the
entry indices are frame class ids, which means that we're reporting some display
list arena entries as frames, which is obviously wrong.

Cleanup a bit nsPresArena to remove the custom id concept, and report also
individual display item type memory usage.
