Add Kokkos_Clamp.hpp & Kokkos_MinMax.hpp to the list of public standalone headers

[nliber]

From release 4.3:

Add Kokkos_Clamp.hpp & Kokkos_MinMax.hpp to the list of public standalone headers, to correspond with https://github.com/kokkos/kokkos/pull/6687.

Specifically, it should be added to https://kokkos.org/kokkos-core-wiki/ProgrammingGuide/Compatibility.html (and Kokkos_Assert.hpp should be added as well) and documentation for clamp to https://kokkos.org/kokkos-core-wiki/API/core/utilities/min_max_clamp.html.

We probably want to add a specific documentation page for public standalone headers.

The headers are mentioned in the notes https://kokkos.org/kokkos-core-wiki/API/core/utilities/min_max_clamp.html#notes
