Move some CSS properties to match Gecko's representation
Fixes#10403. Animation had an extra transition-delay property, which was also moved to Box. Let me know if I should squash the commits.

Reduce size of layout::fragment::Fragment struct
This reduces the size of the SpecificFragmentInfo enum from 48 to 24.

ComputedValues is now ServoComputedValues
This is the first part of #10185. More to follow. I have built this locally with both servo and geckolib without errors; let's see if it succeeds on all platforms as well.

layout: Only take nonnegative margins into account when estimating inline placement of floats.
Otherwise, the heuristics can pass even when there are no floats,
causing block formatting contexts to be speculated to be flowing around
floats that don't exist!
Closes#10237.

Restore stripped whitespace before reflowing text fragments
Fixes#10200. r? @pcwalton
Note: The reftest uses a transition of non-zero duration, because I couldn't find any other way to reproduce the bug. Unfortunately this makes it unreliable in debug builds. I tried to fix this using reftest-wait with setTimeout and requestAnimationFrame, but it still wouldn't complete the animation consistently. To make the test work in debug builds we may need `transitionend` events (#10245) or a different way to reproduce the bug.

Highlight selected text in input fields
Fixes#9993. This does not yet allow stylesheets to set the selection colors; instead it uses a hard-coded orange background and white foreground.

speculation code.
The old code tried to do the speculation as a single bottom-up pass
after intrinsic inline-size calculation, which was unable to handle
cases like this:
<div>
<div style="float: left">Foo</div>
</div>
<div>
<div style="overflow: hidden">Bar</div>
</div>
No single bottom-up pass could possibly handle this case, because the
inline-size of the float flowing out of the "Foo" block could never make
it down to the "Bar" block, where it is needed for speculation.
On the pages I tried, this regresses layout performance by 1%-2%.
I first noticed this breaking some pages, like the Google SERPs, several
months ago.
layout: Allow floats to have negative ceilings due to negative margins.
This fixes `margin-collapse-104.htm`, which is currently accidentally
passing due to lack of #10085. When that PR lands, then that will become
a representative test case.

After #10021, `LayoutThread::repaint` no longer forced a repaint because of
the `restyle_damage` check. This patch adds the correct restyle damage and
fixes#10163.
Generalize the style structs
This allows geckolib to pass gecko style structs and have the style system write to them directly, provided we implement all the traits.

This changes headless operation to strictly be a runtime option, rather
than a compile-time one. Note that the old headless version still relied
on a display server to support WebGL, while it now requires one all the
time.
Fixes#8573
Canvas cleanup
This PR cleans up the layerization infrastructure for canvas, which was unused, and removes unused dependencies.
It also takes in account my recent username change to update angle's dependency (offscreen_gl_context requires extra work due to webrender depending on it).
