AxisTensor components from Int to Float

[Sbozzolo]

ClimaAtmos comes with this note/code:

# In order to specify C2F operator boundary conditions with 0 instead of FT(0),
# we need to tell ClimaCore how to convert AxisTensor components from Int to FT.
# TODO: Move this monkey patch to ClimaCore in the next release.
using ClimaCore.Geometry: AxisTensor, components
AxisTensor{T′, N, A, S′}(a::AxisTensor{T, N, A, S}) where {T, N, A, S, T′, S′} =
    AxisTensor(axes(a), S′(components(a)))
Base.convert(::Type{AT}, a::AxisTensor) where {AT <: AxisTensor} = AT(a)

I don't understand it, but it seems to imply that something should be done on the ClimaCore side.

This was fixed/removed from ClimaAtmos (I'm not sure when, but I don't see it anymore).
