Extending non-standard http methods in Nest

Describe the solution you'd like

Fastify 5 has a new approach regarding non-standard http methods: fastify/fastify#5567.

Wouldn't it be interesting to mimic this behavior within Nest?

Specifying and allowing the use of the body for each of the methods would be really interesting

Teachability, documentation, adoption, migration strategy

Have a @method('Propfind') decorator for example and/or allow the declaration of the use of these methods at bootstrap.

What is the motivation / use case for changing the behavior?

Rather than embedding all non-standard methods in each adapter, allow these methods to be declared at startup or through the use of a special decorator.

This would allow to anticipate some requests regarding methods, including mine about webdav methods: #13278
