Expose -moz-context-properties on stylo
<!-- Please describe your changes on the following line: -->
Gecko already exposed `-moz-context-properties` behind pref `svg.context-properties.content.enabled`. I think we should do the same thing on stylo and make the reftests of `context-fill` and `context-stroke` pass.

We simply implement ToCss for Option<T>, printing nothing if the value is None,
and we then use SequenceWriter to skip writing of separators around empty parts.
This fixes another rAF bug, that is being exposed by the previous
two commits. Previously, the fake timer callback would only be
set if we were being called from a non-rAF event handler.
Now, if we're in fake / spurious mode, unconditionally set the one
shot timer.
Otherwise, notify the compositor that animations are present if
we're not currently in a rAF callback.
This patch doesn't modify any of the code because making a few things pub. I
did this first to make the next patch easier to audit.

This makes the code easier to work with, and fixes a bug where we don't currently
reject pseudo-elements within :not().

This patch is the last one of bug 265894.
It fixes two things:
1. Do not cross shadow tree boundary while matching rules.
2. Change display value to 'inline' while cloning a root symbol element instance.

style: Have OneOrMoreSeparated replace OneOrMoreCommaSeparated.
**NOTE** The alternative for me is just to duplicate the ToCss code, which is not bad and is less code changed! Don't know what others would think, though. Looking for feedback!
A future patch series has some values that should be separated by spaces. This
allows us to re-use the code for serialization, but the types do get a little
clunky. The separator is now indicated with an associated type.

stylo: Bug 1369625 - Make stop-color, flood-color, lighting-color animatable.
This is an interdependent patch of Bug 1369625. We make stop-color, flood-color, and lighting-color animatable by using IntermediateRGBA as the animation value type, just like 'color'
attribute. On the Gecko-side, we enable/add the reftest of them and update WPT expectations for these properties.
