Drop obsolete GST_VAAPI_IS_xxx() helper macros since we are no longer deriving from GObject and so those were only checking for whether the argument was NULL or not. This is now irrelevant, and even confusing to some extent, because we no longer have type checking. Note: this incurs more type checking (review) but the libgstvaapi is rather small, so this is manageable.
