Add Phlex::HTML#render for rendering a component into a String

[marcoroth]

I'm not sure if this was left out on purpose, but I feel like having a static render method shorthand for Phlex::HTML to render the component into a string reads a lot nicer compared to having to instantiate the class and calling call after, especially when working with blocks.

For example, if you are are using Phlex components for Turbo Stream/CableReady payloads:

respond_to do |format|
  format.turbo_stream { 
    render turbo_stream: turbo_stream.replace("#posts", Views::Posts::Index.new(posts: Post.all) { ... }.call ) 
  } 
end

vs.

respond_to do |format|
  format.turbo_stream {
    render turbo_stream: turbo_stream.replace("#posts", Views::Posts::Index.render(posts: Post.all) { ... }) 
  } 
end

Let me know if you feel like this is a valuable addition.

Looking at your specific example, I think the turbo_stream.replace method should accept a renderable as its argument.

That aside, I can definitely see value in having a render class method on Phlex views. I like that name, but I think it should possibly be an alias for a call class method so Phlex views classes can be callable.

This is going to be very useful when I tackle integrating my Phlex views with dry-system.
