Unable to log into chase.com on iPad when DeviceMotionEvent API is di…

<rdar://problem/48423023>

Reviewed by Geoffrey Garen.

Add site-specific quirk for chase.com on iOS where we fire a dummy DeviceMotionEvent if the page
tries to register a "devicemotion" event listener and fails because the API is disabled. This is
needed to unblock the site and proceed with the login flow.

Unfortunately, document()->settings().needsSiteSpecificQuirks() is false on iOS so I could not
guard the quirk behind this flag.
