1820407 - Serialize NaN and infinity angles as per spec

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Oliver Medhurst [:canadahonk]]

Angles like NaN and infinity (and -infinity) should be serialized properly as per spec, see WPT tests for examples.

Many various WPT tests check for this behavior (some under interop 2023, some not):

• https://wpt.fyi/results/css/css-values/acos-asin-atan-atan2-serialize.html (interop 2023 mathfunctions)
• https://wpt.fyi/results/css/css-values/calc-infinity-nan-serialize-angle.html

NaN, infinity, and -infinity angles should be specially serialized.
Also adjusted WPT test expectations, 36 newly pass :tada:
