Partial fix for #12415: expose Canvas interfaces
<!-- Please describe your changes on the following line: -->
Fix interface exposure per [the specs](https://html.spec.whatwg.org/multipage/scripting.html#2dcontext).
One lingering question I have is if [`CanvasPath`](https://html.spec.whatwg.org/multipage/scripting.html#canvaspath) needs to be added to `interfaces.worker.js` since it *is* exposed to the `Worker` environment. I tried adding it to the `interfaces.worker.js` list but it failed tests at https://github.com/servo/servo/blob/master/tests/wpt/mozilla/tests/mozilla/interfaces.js#L82

border box positions and transforms into account.
Clipping region computation now follows a simple process: (1) in the
parent's coordinate system, parents store appropriate clipping regions
into children; (2) each child moves its clipping region to its own
coordinate system if necessary.
Because clipping region computation is now based on stacking-relative
border box positions and the `transform_rect` method, it can handle
`position: relative` offsets and more types of transforms, such as
scaling.

Closes#13753.
resources: Avoid using `:matches` in `presentational-hints.css`, since we don't support it.
Based on IRC discussions, this was determined to be an acceptable
stopgap in lieu of implementing `:matches`, which has complicated
precedence rules.

fragments if `overflow` is not `visible` per CSS 2.1 § 10.8.1.
Additionally, this patch reverts the change introduced in #12642 in
favor of the spec-compliant behavior described above. This patch also
removes the `inline_block_overflow.html` reftest introduced in #3725, as
the behavior it expected contradicted CSS 2.1 (and in fact the test
fails in Gecko).
The changes that this patch makes to `input_selection_a.html` and
`input_selection_incremental_a.html` are necessary workarounds to make
the tests pass in light of the fact that Servo's UA stylesheet applies
`overflow: hidden` to `<input>` elements. I believe that the changes are
not necessary in other rendering engines because they hard-code
`overflow: hidden`-like behavior for `<input>` elements, while Servo
uses the actual CSS `overflow: hidden` behavior. As far as I can tell,
Servo's behavior is arguably more spec-compliant, but it remains to be
seen how Web compatible it is.

10.8, and implement `vertical-align: middle` per CSS 2.1 § 10.8.1.
`InlineMetrics` has been split into `InlineMetrics` for fragments and
`LineMetrics` for lines. Both structures' fields have been renamed in
order to more clearly delineate the difference between *space* and
*content*. Vertical positioning of fragments has been reworked to take
margins and borders into account only for replaced content.
This patch fixes the `vertical_align_super_a.html` reftest. Servo now
matches the rendering that Gecko and WebKit produce.
Additionally, this includes a test for the popular inline-block
centering technique described here:

Implement `word-break: keep-all` (#9673)
<!-- Please describe your changes on the following line: -->
Implement the `keep-all` value for the `word-break` property, as specified in [CSS](https://drafts.csswg.org/css-text-3/#word-break-property).
The relevant CSSWG tests (in `tests/wpt/css-tests/css-text-3_dev/html/word-break-keep-all-*.htm`) do not currently pass. As far as I can tell, this is because the tests use some JavaScript code that is not working properly. (But then, it seems that most tests in this directory are failing at the moment. I'm not sure what can be done here for now.)
