[css-conditional-5] Support @supports named-feature()
rdar://183688843
https://bugs.webkit.org/show_bug.cgi?id=320705
Reviewed by Tim Nguyen.
This patch implements parsing support for @supports named-feature().
The supported name features are hardcoded; it's expected that features
will be added rather sparingly (at most one or two yearly), and only
when it's implemented in WebKit.
Test:

*
LayoutTests/imported/w3c/web-platform-tests/css/css-conditional/at-supports-named-feature-001-expected.txt:
- Test progression.
*
LayoutTests/imported/w3c/web-platform-tests/css/css-conditional/at-supports-named-feature-001.html:
- Add some invalid test cases.
- Fix a bug where the test uses `Boolean.prototype.toString` to
serialize a string, but that method returns "false" for every
input, including `true`.
