Precomputing the skipBEnd bit is odd / wrong. Using the PreReflow
version causes no regression, and allows us to simplify the code.
It also reverts the test annotations added to bug 1675376 which were
caused by the extra argument to GetLogicalSkipSides() somehow.

This patch is generated via the rename functionality in my editor; add
`mozilla::` prefix to `OverflowAreas` in headers; and remove the
`OverflowType` alias added in Part 1.

Both PresShell() and PresContext() are cached in nsIFrame. This
simplifies the setup for the callers to
nsCSSFrameConstructor::CreateContinuingFrame().

At first glance, it might look like this would change behavior, since
FinishReflowChild passes aReflowInput to DidReflow, which in turn
notifies aReflowInput's mPercentBSizeObserver. However, if you examine
how the mPercentBSizeObserver is propagated, it can only be set for the
anonymous block wrapping the children of table cells, the children of
table cells, or additionally a child of a table wrapper frame that has
it set (i.e., a table or its caption, when logically a child of a table
cell). Since all of the frames for which this is being changed are
either internal table elements that are inside of the table, or are
things that can never be a descendant of a table at all, there should be
no change in behavior.

This is the main performance improvement, and means that we no longer have to iterate all the cells for each column.
It has a couple of behaviour changes:
The first is that we no longer apply stacking context effects (like opacity) to column and column group backgrounds.
I believe this is correct as per both CSS2.1 Appendix E, and css-tables-3 (quoted in nsTableColFrame::BuildDisplayList).
This matches the behaviour of blink and WebKit.
We also previously created items in column,row ordering, whereas now they will be in row,column. In cases where two cells
overlap (using rowspan and colspan to extend multiple neighbours in to the same place) this can render backgrounds in a
different order, but the new behaviour matches blink and WebKit.

This also changes behaviour a bit, previously we interleaved column and column group backgrounds. where we now put all the column group backgrounds behind all columns.
I believe this is the correct ordering as per CSS2.2 Appendix E.
Column backgrounds can overlap when using 'span', and we now render this in a different order, but this matches what other browsers do.

Most of the code in DisplayGenericTablePart was all within a per-class if statement, so it doesn't add much value, and makes the control flow harder to understand.

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

Also move the definition of nsRowGroupReflowState from .h into .cpp as
other two classes did since forward declaration in header is enough.
