Bug 253819 – Refactor list-style-type conversion

• Component: CSS
• Status: RESOLVED FIXED

[Vitor Roriz]

list-style-type is currently used to set a list style type and a list style string value. Currently, the StyleBuilderCustom always sets both values together.
This refactoring will introduce a new type to explicitly associate these values, ListStyle, with a type and a name (string value). 
This is a preparation for @counter-style, since list-style-type's associated to custom-ident will always have CustomCounterStyle as ListStyleType (ListStyle.type) and
will rely on the ListStyle.name to differentiate between the counter-styles.
