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.

For now I added everything to the same bucket, but I wrote this so it should be
easy to add more buckets as needed (either to mArenaSizes, or more specific ones
like the style system has). But this is probably enough for now.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

This patch does the following.
- Moves nsWindowSizes from nsWindowMemoryReporter.h to its own file,
nsWindowSizes.h, so it can be included more widely without exposing
nsWindowMemoryReporter.
- Merges nsArenaMemoryStats.h (which defines nsTabSizes and nsArenaMemoryStats)
into nsWindowSizes.h.
- Renames nsArenaMemoryStats as nsArenaSizes, and nsWindowSizes::mArenaStats as
nsWindowSizes::mArenaSizes. This is the more usual naming scheme for such
types.
- Renames FRAME_ID_STAT_FIELD as NS_ARENA_SIZES_FIELD.
- Passes nsWindowSizes to PresShell::AddSizeOfIncludingThis() and
nsPresArena::AddSizeOfExcludingThis(), instead of a bunch of smaller things.
One nice consequence is that the odd nsArenaMemoryStats::mOther field is no
longer necessary, because we can update nsWindowSizes::mLayoutPresShellSize
directly in nsPresArena::AddSizeOfExcludingThis().
- Adds |const| to a few methods.

This switches over layout's usage of PLArena to ArenaAllocator. This allows
us to build more files in unified sources and gets rid of various CONST masks.

This makes it clearer that, unlike how SizeOf*() functions usually work, this
doesn't measure any children hanging off the array.
And do likewise for nsTObserverArray.

This is similar to bug 1038488, which did the same for style structs.
This means the entire path from frame to style struct should be
allocated using frame IDs or object IDs.
"new nsFrameList()" becomes "new (shell) nsFrameList()".
"delete list" becomes "if (list) list->Delete(shell)" - note also that
an additional assertion was added that list is empty when deleted.
"nsAutoPtr<nsFrameList> list(StealSomeFrames())" becomes
"AutoFrameListPtr list(aPresContext, StealSomeFrames())"
