Remove forward compat parsing of PackedVector4Array in binary format 

The logic I implemented was lacking, and actually it's not useful as binary files saved by Godot 4.3
are not recognized due to the `ver_major > VERSION_MAJOR` check.

So even if the format version was unchanged, such files would still not be readable in 4.2.
