Related to rails#57781 As reported in rails#57781, new calls to `#render_in` emit `render_template.action_view` Active Support notifications, which themselves cause a spike in object allocations. This commit explores an alternative that preserves the behavior introduced in [rails#50623][] (support for passing `:locals` at the `#render_in` call-site) without also emitting `render_template.action_view` notifications. Rather than rely on the `ActionView::Renderer` instance returned by the `ActionView::Helpers::RenderingHelper#view_renderer` invocation, construct an instance of `Template::Renderable` and invoke `#render` on it directly.
