Prompt for name when using extract refactoring assists

In typescript, extracting a variable / function / etc. allows you to enter a name for the just created extraction. It would be nice to do the same in RA for functions, modules, variables, etc.

Playing with the extract_variable:

if let Some(cap) = ctx.config.snippet_cap {
    if let Some(ast::Pat::IdentPat(ident_pat)) = let_stmt.pat() {
        if let Some(name) = ident_pat.name() {
-            edit.add_tabstop_before(cap, name);
+            edit.add_placeholder_snippet_group(
+                cap,
+                vec![name.syntax().clone(), name_expr.syntax().clone()],
            )
        }
    }
}

SourceChangeBuilder::add_placeholder_snippet_token doesn't seem quite right for this. Instead of a single edit location which applies to both places when the edit is confirmed, this method makes two edit locations that are edited simultaneously.

I'm not quite sure what the right terminology to use to find the functionality here, so seeking some guidance on what to do to make this work.

Edit: this UX is provided by the rename symbol function, but I'm not sure how that would fit in to the extract refactoring.

Start at the extract_variable assist and SourceChangeBuilder's add_placeholder_snippet_token and add_placeholder_snippet_group APIs. Compare how rename symbol provides linked editing, then determine how that behavior should apply to extracted functions, modules, and variables. Done means extraction assists prompt for a name and update linked occurrences together.
