Most of this patch is just mechanical changes, but note that this patch
now makes the mFlags in scrollbar-container nsDisplayOwnLayer instances
have one of the direction bits set. As a result, this requires changing
the implementation of nsDisplayOwnLayer::IsScrollThumbLayer().

ScrollDirection variables for which NONE was a valid value are replaced with
Maybe<ScrollDirection>.
I also took the opportunity to change the remaining ScrollDirection
enumerators to eTitleCase as per style guide.

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.

Also add a comment to AsyncDragMetrics documenting that mScrollbarDragOffset
is relative to the thumb's start offset.

To conserve space in LayerAttributes, we only store the extents along the
relevant axis.

This flag is set to false if there are any conditions that only the main
thread knows about that prevent the thumb from being async-dragged.

The patch also renames Layer::SetScrollbarData() to Layer::SetScrollThumbData()
for clarity.

Updating hit testing trees is very expensive for many layers, and often
layer properties that change don't necessitate hit testing tree updates.
While layer tree structure changes do, we can be smarter about
individual layer attributes.
