[red-knot] fix non-callable reporting for unions (#16387)
Minor follow-up to https://github.com/astral-sh/ruff/pull/16161

This `not_callable` flag wasn't functional, because it could never be
`false`. It was initialized to `true` and then only ever updated with
`|=`, which can never make it `false`.

Add a test that exercises the case where it _should_ be `false` (all of
the union elements are callable) but `bindings` is also empty (all union
elements have binding errors). Before this PR, the added test wrongly
emits a diagnostic that the union `Literal[f1] | Literal[f2]` is not
callable.

And add a test where a union call results in one binding error and one
not-callable error, where we currently give the wrong result (we show
only the binding error), with a TODO.

Also add TODO comments in a couple other tests where ideally we'd report
more than just one error out of a union call.

Also update the flag name to `all_errors_not_callable` to more clearly
indicate the semantics of the flag.
