Because `ActionText::Content.renderer` is implemented as a `thread_cattr_accessor`, any default value set in the main thread will be inaccessible from other threads. Therefore, use a `cattr_accessor` to store the default renderer, and fall back to it when `renderer` has not been set by e.g. `with_renderer`. Fixes #40757.
