Add FPDFAnnot_GetFormFieldAtPoint() and embedder tests.
Given a point on a page, this method returns the interactive form
annotation whose rectangle contains that point. If there is no such
annotation, nullptr is returned. FPDFPage_CloseAnnot() must be called
after the annotation this method returns is no longer needed.
The tests for this method use the returned annotation to check its
interactive form annotation flags via
FPDFAnnot_GetFormFieldFlags().
