[fill-stroke] [filter-effects] [css-color] percentage opacity
- RESOLVED: No change to spec
We should probably prioritize adding percentage opacity (in all the places it's allowed) relatively highly since once other engines add it, we're likely to start hitting compat problems reasonably quickly. It should also be pretty simple to do.

This bug will use <alpha-value> for these properties:
-moz-window-opacity uses Opacity type, so for consistency, I will also update it.

The following properties accept <alpha-value> [1], which is
"<number> | <percentage>", so we update the parser, spec links, and
their web-platform-tests.
- opacity
- flood-opacity
- fill-opacity
- stroke-opacity
- stop-opacity
- -moz-window-opacity
Besides, shape-image-threshold [2] still only accepts <number>, so we need
to support a different version of Opacity::parse().
