Add isValid to Binder (#8274)
* Add isValid to Binder
isValid enables you to check the current validation
status of a given Binder, without firing events or invoking
handlers.
This patch also clarifies the javadocs of StatusChangeEvents'
hasValidationErrors.
* Throw in Binder.isValid if no bean is set and bean validators exist
* Add test cases to BinderTest
