Before this change, only elements inside the shadow root tree were scanned for the
draggable=true attribute. We now check the flattened tree instead so an element
inside a shadow root can start a drag for an element containing the shadow root.

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

We have a better type to represent "a coord or nothing", and that's Maybe.
This code is shorter, and I think reads generally better / is less easy to
misuse.

This patch moves some `enum` in `nsIPresShell` which are in public scope into

This patch creates new header, `mozilla/PresShellForwards.h`. It should have

Additionally, this moves all `enum`s and `constant`s in them into the new file

After introducing column-span, the ColumnSetWrapperFrame can have more
than one ColumnSetFrame children if there's any column-span:all child.
Thus we cannot use "height:100%" to pass block size information down to
the -moz-column-content's children.
Skip column span wrapper in nsIFrame::IsBlockWrapper() so that the
percentage column-span:all works.
Before this patch, the height of column contents are set to 100% of the
multicol container, so if the previous in-flows of column content
anonymous boxes consume all the height, later in-flows's height are all
0. In this patch, we don't restrict column-content's height, so their
height are calculated based on their children's height.
column-contain-1a.html passes because it can now correctly calculate the
union of all the column content's rect to find the correct sticky
positioning.

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.

This patch extracts two additional CompositorHitTestInfo flags from the
eDispatchToContent flag; eApzAwareListeners for elements that have
APZ-aware listeners, and eInactiveScrollframe for inactive scrollframe
or unlayerized scrollthumbs. The eDispatchToContent is then renamed to
eIrregularArea to reflect the fact that it is used for irregular-shaped
areas that require main-thread hit-testing.
Additionally, it is important to note that when using the non-WebRender
codepath, all three of these flags still end up gettings squashed into
the "dispatch to content" region on the EventRegions; when APZ
reconstructs a CompositorHitTestInfo it will turn anything in this
region back into an eIrregularArea. So this is a lossy round-trip
conversion for the non-WebRender case. However it should still result in
correct behaviour because the semantics of eIrregularArea result in APZ
relying on the main-thread to do hit-testing and so any APZ-aware
listeners and inactive scrollframes are also handled by the main-thread.

If the frame supports it (stacking context + containing block for fixed), and a descendant was
modified, we would have created an override dirty region with just the area of that descendant.
In the case where no descendants are modified, we should use an empty rect, rather than
the area inherited from our parent.
This fixes the case where we forcibly build position:fixed frames (since they might async
scroll differently to the rest of the page), but we only need to build the container item,
not the whole frame subtree within it.
Added a test that shows us building the non-intersecting position:fixed, but not items within it.
