Add general approach to send form snippets to client

While HTMX support in DreamForm is a really nice feature it’s not as useful if HTMX is not part of a sites frontend stack : )
Personally i use AlpineAjax for components where a similar behaviour is required.

It’s currently possible to re-create the same behaviour with AlpineAjax and using htmx mode, i would love to see DreamForm implementing a more general approach to just send the form snippet, instead of the whole page, back to the client when a form is send to the server.

This could break the current out-of-the-box behaviour for HTM, cookbook articles could add documentation on how such behaviour can be realised with DreamForm.

From what I've gathered, Alpine Ajax does not have an equivalent for some features required for the Htmx integration, so this isn't a simple addition.

The most lacking feature in AlpineAjax was a missing equivalent to HTMX hx-vals attribute. I’ve created a simple test AlpineAjax DreamForm integration for a site i’m planing to use it. I did not check for multi-step support and proper testing is still required.

The solution to the currently missing hx-vals attribute is an Alpine Form component that will append the values to the request issued by AlpineAjax.
