Replace RecursiveApply functions with AutoBroadcaster wrappers

[dennisYatunin]

Replaces the RecursiveApply module with a new interface that follows the opposite design pattern: instead of defining functions for Tuples and NamedTuples that need to be called in Fields, Operators, MatrixFields, and sometimes even in ClimaAtmos, we can now use a wrapper for Tuples and NamedTuples that behaves the same way when passed to any standard math function. This should make it easy to decouple iteration over field variables from most of ClimaCore's internals.

The new interface can be extended to any iterator type T by defining the method is_auto_broadcastable(::T) = true, as long as T is compatible with UnrolledUtilities.jl. The @auto_broadcaster_args annotation provides a convenient shorthand for extending the new interface to arbitrary functions of Numbers or AbstractArrays, automatically broadcasting those functions over Tuples, NamedTuples, and AutoBroadcasterss. This annotation can also be used to add methods for any other type T, with the resulting behavior depending on whether is_auto_broadcastable is true for that type.

This looks good to me. It's nice to get rid of RecursiveApply. I didn't have any significant comments.
