Check if Fortran interfaces are enabled

[gardner48]

When using an existing AMReX install, the top level CMake always calls enable_language(Fortran) so the Fortran compiler is found even if the Fortran interfaces are disabled.

@ax3l Did something change in pyamrex?

Ah, this is a breaking change from AMReX development from last week (AMReX-Codes/amrex#3956). I updated the interface to pull it in it today: AMReX-Codes/pyamrex#324

Restarting CI now for the PR here.

Thanks! :)
