Cleanup: unify method parameters for virtual arrays 

This makes `GVArrayImpl` and `VArrayImpl` more similar.
Only passing the pointer instead of the span also increases
efficiency a little bit. The downside is that a few asserts had
to be removed as well. However, in practice the same asserts
are in place at a higher level as well (in `VArrayCommon`).
