This adds a CSSVariableDeclarations object to nsRuleData and adds a
MapRuleInfoInto function to CSSVariableDeclarations so the can copy
variable declarations into a nsRuleData's object. We call that from
Declaration::Map{Normal,Important}RuleInfoInto.
We make HasImportantData return true if we have important variables
but no important non-custom properties on a declaration, since that
is used to determine whether we have a rule node for important
declarations. This means MapImportantRuleInfoInto can no longer
assume that mImportantData is non-null.
