Add support for position:sticky
This leverages the position:sticky support in WebRender to bring basic
support for position:sticky in Servo. There are still some issues with
nested sticky flows as well as a few other corner cases. Tests are
imported from WPT and can be removed once we update to the latest
version.

stylo: Store location information for keyframe rules.
So far, we only store location info for the whole Keyframes block, not for each
of the keyframe rule. Without this info, the devtool can't present the rules
on the devtool panel properly.
In this patch, we collect the source location info while parsing keyframe selector.
The binding function, Servo_KeyframesRule_GetKeyframe, is also fixed (and renamed
to Servo_KeyframesRule_GetKeyframeAt to match the fix) to accept line and column
parameters from Gecko, so we can pass/set them with the source location from Servo.
This is the servo part of [Bug 1394994](https://bugzilla.mozilla.org/show_bug.cgi?id=1394994).

Reduce usage of fmt in serialization and error reporting
`format!` and `write!` create a somewhat-heavyweight `Formatting` struct and use dynamic dispatch to call into impls of `Dispaly` and related traits. The former also allocates an intermediate string that is sometimes unnecessary.
I started looking into this from https://bugzilla.mozilla.org/show_bug.cgi?id=1355599, but I expect the impact there will be small to insignificant. It might be a slightly less so on parsing (error reporting).

When collecting style statistics, we have this path that moves the TLS contexts
to be dropped before the local context.
Since destroying the TLS context runs the sequential task queue, that means that
sequential tasks would be executed sooner than usual, before we drop the main
thread TLS context.
Since we have that reuse of the main thread context's bloom filter, and some
tasks end up creating one (Servo_StyleSet_GetBaseComputedValuesForElement, I'm
looking at you), we may borrow the bloom filter before we're done with it on the
traversal code path.
This was hitting on YouTube, when DUMP_STYLE_STATISTICS was used.
I want to play with autogenerating style structs, and color is the smallest
struct out there.
However, moving it out of the mako file is a requirement. This patch does that.
PR #18103 disallowed interpolation between fill:none and fill:none, but that change was regressed by the refactoring in PR #18239.
This patch restores the intended behavior, disabling animation of SVGPaintKind::None.
stylo: Remove calc support from media queries
Gecko currently doesn't support calc inside media queries. We should
also remove the calc support temporarily for parity with gecko. We can
add this support back in next releases.

Take a `u8` pointer and a length instead of `nsACString` pointer from Gecko.

Make the order of rules in DevTools be the specificity order.
We insert rules with any important declaration into rule tree twice,
one for the normal level and another for the important level. And
when we fetch them from rule tree, we skip the important one to
make the order be the specificity order.

Properly set default direction of prefixed linear gradients
The default linear gradient direction is `to bottom`. This correspondes to
`top` keyword in prefixed linear gradients. We should preserve the default value.
