[line-clamp] Update line-clamp, max-lines and block-ellipsis to the latest
specification
https://bugs.webkit.org/show_bug.cgi?id=323605
Reviewed by Tim Nguyen.
Update line-clamp, max-lines and block-ellipsis to the latest specification
according to this github issue [1]:
max-lines = <integer [1,inf]> || auto
block-lines = no-ellipsis | ellipsis | <string>
line-clamp = none | [<integer [1,∞]> || <'block-ellipsis'>] -webkit-legacy?
To support this, max-lines parsing can now returns a CSSValueList and likewise
line-clamp parsing can result
in a CSSValueList if both auto and an integer are provided.
The current WPT tests expect this and chromium already updated these properties
to match the specification.
