Customize: Pass `WP_Customize_Setting` instance as second argument to `customize_value_{$id_base}` filter.

Adds parity with setting instance being passed as second argument to `customize_sanitize_{$id}` and `customize_sanitize_js_{$id}`. Allows the actual ID of the (multidimensional) setting value being filtered to be inspected.

Props celloexpressions, westonruter.
Fixes #36452.
