adds malli defendpoint + linting + tests (#27314)

The new macro is called defendpoint. The previous defendpoint is now defendpoint-schema, as per @camsaul's idea. It'll make it easier to realize that we should use the Malli version of defendpoint going forward.

* adds malli defendpoint + linting + tests

- I decided to add a new defendpoint macro -- it is nearly exactly the
  same as `defendpoint`. If the duplication is an issue I can handle that too.

* malli-defendpoint -> defendpoint-malli

* defendpoint -> defendpoint-schema

* defendpoint-malli -> defendpoint

* fine tuning error messages + comments

- fix kondo config

* put back dox-for-plumatic

* fix name collision

* adds local malli description ns + test

* update alias in test

* linting fix

* linting fix pt. 2

* hook up umd/describe
