serialize font: to empty on non-default subprops
Fixes font shorthand serialization so that it serializes to "" when non-default subproperties are defined. These subproperties are those defined in #15033.
Adds tests:
- font_should_serialize_to_empty_if_there_are_nondefault_subproperties
- font_should_serialize_all_available_properties
The second test was previously commented out and underwent some cleanup to make it run.

Fixes font shorthand serialization so that it serializes to "" when
certain subproperties of the font shorthand are set to non-default
values. These subproperties are:
- font-size-adjust
- font-kerning
- font-variant-caps
- font-variant-position
- font-language-override
Additionally, enable the above subproperties in the tests.

Before this patch, we store each computed values in a hashtable,
nsRefPtrHashtable<nsUint32HashKey, RawServoAnimationValue>, for all
KeyframeEffectReadOnly on an element, and convert the ServoAnimationValues of
the hashtable into an nsTArray<ServoAnimationValue*> and then convert
the ServoAnimationValues of the nsTArray into PropertyDeclarationBlock
in rust. This way was really inefficient.
In this patch, we store the computed values into AnimationValueMap and
convert all AnimationValue in the map into PropertyDeclarationBlock
after EffectCompositor::GetAnimationRule.
We need to convert all AnimationValue (AnimationValueMap) on an element
to PropertyDeclarationBlock in order to push the value inside the CSS cascade.
Two reasons we did not add the function in AnimationValueMap:
1) All members of PropertyDeclarationBlock are private.
2) Rust does not allow us impl for type alias, so if we do impl the function
in AnimationValueMap we need to make AnimationValueMap as a tuple or struct.
Current Gecko composes all of effects in the composite order at once.
We can put each computed value into this AnimationValueMap every time composing
an effect.
If an element has only CSS animations we don't need to get transition rule,
and vice versa. This will be used when we implement eRestyle_CSSAnimations
and eRestyle_CSSTransitions.
