Add hasattr checks for remaining protocol isinstance checks

This PR is a successor to #7502. The proxied-read case appears in the standard library which points to it being a pretty well established pattern. A quick search shows there are two other places this was missed in.

Rather than put `or hasattr(data, "read")` everywhere we use want to use `SupportsRead`, this combines it into a single check that scopes typing correctly for proxy objects. That should hopefully avoid missing it for future checks as well.
