  [visionOS] WKContentView doesn't relinquish first responder after tapping Safari unified field

Reviewed by Wenson Hsieh.

The keyboard request dismissal can happen *after* the firstResponder chain
is affected by the dismissal and in fact this does happen on visionOS. By
also checking _isEditable we ensure that even if the firstResponder is the
content view but was not before the dismissal, we don't incorrectly set the
keyboard lock to true (blocking the next attempted resignation), as
_isEditable is not yet true in this case.

* Source/WebKit/UIProcess/ios/WKContentViewInteraction.mm:
(-[WKContentView _keyboardDidRequestDismissal:]):
Require the content view is firstResponder AND editable to block the next
firstResponder resignation attempt.
