margin properties are allowed in an @page rule. Other properties are ignored.

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.

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.
Similar to animations and backgrounds, multiple transitions should be
serialized as a list of shorthand values only if the number of values
for each longhand property is the same. Otherwise we default to the
longhand serialization. Fixes#15398
Similar to animation, the serialization of multiple backgrounds should
return the longhands serialization if there are an unequal number of
values for the required properties.
Fixes#15398
The previous commit did most of the work here of updating the algorithm
to skip shorthands if a shorthand value was an empty string. This commit
just updates animations LonghandToSerialize's implementation of
to_css_declared to write an empty string value if the list lengths
differ (and updates the test to match).
Refactor outline-style to accept "auto" value in addition to border-style values.
Fixes https://github.com/servo/servo/issues/15207
Refactored as per https://github.com/servo/servo/issues/15207#issuecomment-275171590 .

* `LonghandId` and `ShorthandId` are C-like enums
* `Atom` is used for the name of custom properties.
* `PropertyDeclarationId` is the identifier for `PropertyDeclaration`,
after parsing and shorthand expansion. (Longhand or custom property.)
* `PropertyId` represents any CSS property, e.g. in CSSOM.
(Longhand, shorthand, or custom.)
Using these instead of strings avoids some memory allocations and copies.
Convert column-width to use Either
<!-- Please describe your changes on the following line: -->
