Review Comment:
The main change of this PR is to introduce per-type "InProgressArrays" that
have specializations for each type of array
This PR adds a specialization for StringViewArray (to remove the need for
`gc_string_view_batch`)
In follow on PRs (maybe tickets) we can add specialized versions for
PrimitiveArray, StringArray, etc
