Bug 1373798 - Move HTML dir attribute state into event state flags

Browse source 
* Stop calling SetHasDirAuto/ClearHasDirAuto in input element code
* Introduce event state flags that track the state of an element's dir attribute
* Rewrite our existing checks for the state of the dir attr on top of the new event state flags
* Add pseudo-classes for matching on the dir attribute states
* Use the new dir attribute pseudoclasses in html.css
