stylo: support all overflow values
overflow:clip doesn't exist, it's just called clip internally. Renamed, and added the other missing values.
I also removed the overflow newtype -- no need for extra code bloat, and it's not protecting us from much.

layout: Force reflow in the sequential fallback of block format context
When reflowing a block format context during the inorder traversal,
propagate restyle damage manually to its children since they were
already reflowed. Also, test the border box to see if it can fit into
floats according to CSS 2.1 § 9.5.

Just use WebRender's ClipId directly. This will allow us to create and
use ReferenceFrames in the future, if we need to do that. It will also
make it easier to have Servo responsible for creating the root
scrolling area, which will allow removing some old hacks in the future.

Instead of passing down a complex clipping region to each item, used
shared clipping to handle overflow:hidden and CSS clips. In addition to
being more efficient, this should also fix quite a few issues related
to absolutely positioned elements.
One existing reftest is slightly modified to avoid tickling a quirk
with the way that WebRender rasterizes masks. We are working out how to
best express these combined masks with the API or need to. The change
does not affect the original subject of the reftest.
Fixes#13109.
Fixes#10151.
Fixes#7575.
Fixes#8074.
Fixes#8780.
When dealing absolutely positioned items, we should use clip of our
containing block, even if our containing block doesn't itself establish
a new overflow clip. Additionally, we need to properly handle
assigning scroll root ids to fragments of inline elements.
We add a test for this behavior.
Update WR (new border code path).
This includes the new border code path for simple (solid) borders.
This gives much higher quality border rendering, including proper
support for elliptical border segments.
The quality on https://github.com/servo/servo is noticeably improved.

Overwrite default RunInfo values with the first real ones encountered.
TextRunScanner::flush_clump_to_list compares the values in the RunInfo object against the ones determined from the current fragment, but these values can be arbitrary defaults that don't mean anything useful.

While we're at it, we also eliminate the 'unknown' dom depth for the
bloom filter. Computing depth has negligible cost relative to the
amount of work we do setting up the bloom filter at a given depth.
Doing it once per traversal should be totally fine.
I originally separated the elimination of unknown dom depth from the
traversal changes, but I got bloom filter crashes on the intermediate
patch, presumably because I didn't properly fix the sequential traversal
for this case. Given that the final state is green, I just decided to
squash and move on.
This is the first step toward removing inherited clips in favor of
scroll roots for handling overflow and CSS clipping. This will allow us
to more easily handle elements that should not be clipped. While we are
still using inherited clips here, we now properly clip some types of
content that wasn't clipped before.
Since for nested inline elements non-inheritable properties are
properly stored in the inline context of an inline fragment, so get
rid of them on the style.
Add full parsing/serialization for mask-repeat and background-repeat
I implemented full parsing and serialization for the mask-repeat and background-repeat style properties. I think some more tests are required but I'm not what I'm missing. I'd appreciate some direction.
I also had to modify some layout code to get my changes to compile. As a result, background-repeat should work individually in both directions now too.
