src: remove unowned usages of GetBackingStore

This removes all usages of GetBackingStore without any entries in the
`CODEOWNERS` file. For the most part this is a pretty straightforward
review; except `SPREAD_BUFFER_ARG` and the changes to `CopyArrayBuffer`.

See the linked issue for an explanation.
