In order to speed up Required/IsRequired(), instead of querying for the
@required attribute, we're now using the NS_EVENT_STATE_REQUIRED flag to know
whether an element's value is required.
For this to work correctly, we need to set NS_EVENT_STATE_REQUIRED earlier,
that is, in AfterSetAttr(), before any consumer of IsRequired(). We also need
to update or clear our required states when input type changes, since we may
have changed from a required input type to a non-required input type or
vice versa.
Note that NS_EVENT_STATE_REQUIRED/OPTIONAL is now part of the
EXTERNALLY_MANAGED_STATES.

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.

Also implements :link, :visited, and :any-link more efficiently, and stops
matching :-moz-read-only in everything that is not read-write, which is kind of
dumb, and probably creates some artifacts.

Since it's not just the EventStateManager that has access to modify
these EventStates bits.
