It was printing `repeat(n, <line-names>)` for number TrackRepeat.
But it should just print n times <line-names> instead.

Fix incremental layout bugs for absolute and cleared elements
Fixes#17307. <del>There were two underlying bugs:</del>
* <del>Nodes were not marked dirty when their style attribute changed.</del>
* BaseFlow flags set during flow construction could get out of sync with the element's style if repair_style was called.

stylo: Fix font-variant-alternates property
`font-variant-alternates` was just parsing values as keywords. But many of the alternates are actually functions instead of keywords. This fixes that.

Bug 1368302 - stylo: possible stack overflow when processing very dee…
…p DOM. r=bholley.
Whilst working with variants of the bloom-basic test for Stylo perf
profiling, I noticed that it is easy to cause Firefox to segfault on DOMs
with a depth of more than about 1500 elements. This fix limits the use of
tail recursion to 150 elements. This isn't externally observable to content
-- we're still completely correct, just not using tail recursion any more.

Implemented paint worklets invoking worklet scripts.
<!-- Please describe your changes on the following line: -->
Implemented the "invoke a paint callback" functionality of paint worklets (https://drafts.css-houdini.org/css-paint-api/#invoke-a-paint-callback).
This PR does not implement the 2D rendering context, and just generates a placeholder image.
