Requiring that UA style sheet-only shorthand properties only have UA
style sheet-only subproperties makes it easier to deal with the
subproperties outside of the CSS parser (which is where the information
about whether a given property is enabled only in UA style sheets is
stored). Similarly for certified app-only shorthands.
This includes removing:
* the box property directional source constants
* the CSS_PROPERTY_DIRECTIONAL_SOURCE property flag
* the CSS_PROPERTY_REPORT_OTHER_NAME property flag
* nsCSSProps::OtherNameFor
* methods on the CSS parser to parse directional box properties and set
the old *-source and *-value properties
* the resolution of logical and physical properties in nsRuleNode during
style computation, since that's now done as part of the cascade in
nsCSSExpandedDataBlock::MapRuleInfoInto
Here we convert the logical padding properties into their new resolved-at-
cascade-time implementations. This involves:
* converting -moz-padding-{start,end} into logical longhand properties
* adding padding-inline-{start,end} aliases for -moz-padding-{start,end}
* converting padding-{left,right} into longhand properties
* removing padding-{left,right}-value and
padding-{left,right}-{ltr,rtl}-source internal properties
The CSS parser and various tests are simplified a bit as a result.
We define a new flag CSS_PROPERTY_LOGICAL to be used for logical longhand
properties and a new CSS_PROP_LOGICAL macro in nsCSSPropList.h to
define them.
When using CSS_PROP to capture all properties, includers must now
explicitly indicate whether logical properties are included or not,
by defining CSS_PROP_LIST_EXCLUDE_LOGICAL (to exclude them),
CSS_PROP_LIST_INCLUDE_LOGICAL (to include them), or CSS_PROP_LOGICAL
(to capture them separately from other properties).

- Implemented boilerplate to add the scroll-behavior CSS property.
- Added layout.css.scroll-behavior.property-enabled preference to
allow the scroll-behavior CSS property to be enabled independently
of the CSSOM-View DOM scrolling api extensions for smooth scrolling.
