expr: seperate expression parsing and building functions
The expression build function currently assumes to be only used from rule context and actually builds rule attributes. Fix that and only build the expression. Also it seems to have been exported by accident, undo that. Additionally, move the expression parsing function from rule parsing and also remove any assumptions about being used in rule context.
