Refactor multibuffer methods for multibuffer range -> buffer range

* Renames `excerpts_for_ranges` to `disjoint_ranges_to_buffer_ranges`, and modifies it to return `MultiBufferExcerpt` since it provides more information and was already being built. * `range_to_buffer_ranges` now returns an iterator, should improve efficiency in a few places. Now implemented by just calling `disjoint_ranges_to_buffer_ranges`.
Remove unnecessary lifetimes on Buffer::diagnostic_group (#22698 )
