Add runtime check for streams in CPDF_Dictionary::SetForInternal()

Disallow objects of CPDF_Stream to be directly added to CPDF_Dictionary
at runtime using a CHECK(). Fix the CPDF_SyntaxParser caller that
violates this check to make the existing test suites pass.

Additionally, include a crafted PDF that also demonstrates this issue as
a pixel test. Since PDFium no longer parses the out-of-spec direct
stream, the crafted PDF renders as blank.
