Store COW strings in CSS parser errors when possible.
This should be a straightforward performance improvement in pages with lots of CSS property values that the parser does not understand.

Replace all uses of the style::stylearc alias with servo_arc.
The `stylearc` alias is left there temporarilly and will be removed completely in a later commit/PR where also `components/style/gecko/generated/structs_{debug|release}.rs` are re-generated (they still use the old alias).

use the old alias).
This patch also removes the duplication of style contexts during the
restyle, because otherwise pointer equality of ServoComputedValues stops
holding (and we assert on that in a few places)
Suppress CSS parser errors for vendor-prefixed properties.
This matches the behaviour of Gecko's CSS parser.

Sync Servo / Gecko image-orientation rounding; pass as enum.
Make Servo's rounding of image-orientation values agree with Gecko's,
and pass orientations directly as an enum instead of as angles.
Depends on a Gecko change to be subsequently landed in m-c.

It was storing both TrackSize and TrackRepeat before and TrackRepeat have to be
converted into sequence of TrackSize during serialization. Instead of doing this
in serialization process(which is hard and hacky), we converted to do this in
parsing process. We were doing this conversion in the ComputedValue conversion.
So we only had to move this process to parsing.
