Addresses #15401
The desired result is for `CSSWideKeyword`s to return false (they are
parsed) and other Custom declaration values to return true (they are unparsed).
Adds tests:
- font_should_serialize_to_empty_if_there_are_nondefault_subproperties
Tests that the font subproperty serializes to an empty string when
certain non-default subproperties are defined.
- font_should_serialize_all_available_properties
Verifies that all properties that the font shorthand can display
will be serialized. This test was previously commented out and has
been simplified.
From https://bugzilla.mozilla.org/show_bug.cgi?id=1347719
This effectively combines the discriminants of the two enums and reduces the
size of PropertyDeclaration by one word.
MozReview-Commit-ID: 9rCRiSVZTQT
Make size_of tests measure stylo and reduce the size of stylo PropertyDeclarations by 16 bytes
Right now they don't, which means that we have four properties making PropertyDeclaration 16 bytes bigger than it should be.
I'm not sure if there's a better way to get these tests to run against stylo than to hoist them into the properties file, but I couldn't figure it out. This seems good enough.

Make text decoration testable and do not serialize initial text-decoration-style
Servo now uses the same name for the text-decoration-line longhand property as Gecko. This was done to enable testing of the text-decoration shorthand.
The text-decoration shorthand has been fixed to not serialize initial text-decoration-style.

Shorthand cannot represent CSS-wide keyword in individual longhands, and
thus we cannot serialize longhand with CSS-wide keyword as part of a
shorthand.
