style: Simplify :dir() implementation

Browse source 
This I noticed while working on the following patches. Shouldn't have
any behavior change: the behavior does in fact match the element state
flag semantics correctly if we do this. We did split the dir flags into
two element bits a while ago.

:not(:dir()) still behaves correctly of course, and we have tests for that.
