Reland "Handle different types of streams in different jpeg source managers"

For streams that are memory backed (stream->getMemoryBase() returns
a non-null ptr and hasLength() returns true), handle the stream
with skjpeg_mem_source_mgr, which directly assigns memory base to
the source manager.  For other non memory backed streams, handle the
stream with skjpeg_buffered_source_mgr, which is renamed from
the old skjpeg_source_mgr with no implementation change.
