Jessica Jong 3342b6100d Bug 1375599 - Change IsDisabled() to look at NS_EVENT_STATE_DISABLED instead of the "disabled" attribute. r=bz 
In order to speed up IsDisabled(), instead of querying for the @disabled
attribute, we're now using the NS_EVENT_STATE_DISABLED flag to know whether an
element is disabled.
It is safe to use the NS_EVENT_STATE_DISABLED flag for the following reasons:
- For form elements, nsGenericHTMLFormElement::IsDisabled() is only called on
  form elements that can be disabled; form elements that can't be disabled
  overrides IsDisabled() to return false directly.
  And, before this patch, NS_EVENT_STATE_DISABLED flag is set by
  nsGenericHTMLFormElement::IntrinsicState() if and only if IsDisabled() in all
  cases when CanBeDisabled() is true, and when CanBeDisabled() is false then
  IsDisabled() is always false and the flag is not set.
- For non form elements, optgroup and option have the flag matching
  IsDisabled(). Note that option's IsDisabled() should also refer to optgroup's
  (if it exists) disabled state, which was not done before this patch.

For this to work correctly, we need to set NS_EVENT_STATE_DISABLED earlier,
that is, in AfterSetAttr(), before any consumer of IsDisabled().
We also need to update the flag whenever the element's parent (e.g. fieldset or
optgroup) disabled state changes and when moving into/out of a parent
container.

Note that NS_EVENT_STATE_DISABLED/ENABLED is now part of the
EXTERNALLY_MANAGED_STATES.
