_coordinate not defined for `LatLong` points

[Sbozzolo]

This leads to problems with Remapper.

  MethodError: no method matching _coordinate(::ClimaCore.Geometry.LatLongPoint{Float64}, ::Val{1})
  
  Closest candidates are:
    _coordinate(::ClimaCore.Geometry.XZPoint, ::Val{1})

    _coordinate(::ClimaCore.Geometry.YZPoint, ::Val{1})

I found that I had to define them like this:

    ClimaCore.Geometry._coordinate(
        pt::ClimaCore.Geometry.LatLongPoint,
        ::Val{1},
    ) = ClimaCore.Geometry.LongPoint(pt.long)
    ClimaCore.Geometry._coordinate(
        pt::ClimaCore.Geometry.LatLongPoint,
        ::Val{2},
    ) = ClimaCore.Geometry.LatPoint(pt.lat)

That is, flipping the value with respect to the order implied by the name. If I have them with the same order, the error is:

  promotion of types ClimaCore.Geometry.LatPoint{Float64} and ClimaCore.Geometry.LongPoint{Float64} failed to change any arguments

This is due to the fact that we typically put longitude as first dimension.
