lsp/completion: support completing to Elem() types

For array, slice, maps and chan candidates, we now support
transforming them to their element type in completions. For example:

    var m map[string]int
    var _ int = m<>

At <> we complete to "m[]" because we see that the map value type
matches our expected type.

Fixes golang/go#46045.
