Description
As discussed in #8724, we should have a way to get `DoubleValueSource` and `LongValueSource` views of multi-valued fields indexed with `SortedNumericDocValues` by using a `SortedNumericSelector.Type`

Research direction
Start by reading the discussion in #8724 and the issue's references to SortedNumericDocValues, DoubleValueSource, LongValueSource, and SortedNumericSelector.Type. Determine the existing value-source and selector entry points, then verify that both requested views can use a selector for multi-valued fields. Done means the views are available with the specified selector behavior and are covered by relevant tests.
