add target AMIP runs on GPU

[juliasloan25]

Purpose

closes #630

Content

• use ClimaAtmos v0.21.0 for gpu-compatible topography
• add amip topography longrun
  • following config/longrun_configs/amip_target_topo.yml
  • set anim:false (not gpu-compatible)
• amip topography + diagnostic edmf longrun
  • following config/longrun_configs/amip_target_topo_diagedmf.yml
  • set anim:false (not gpu-compatible)
• add shortruns for both cases (decrease t_end to 1day)
  • I think we should keep these around with shorter t_end (200secs?) to make sure any future changes don't break these cases
• rename config/model_configs/gpu_target_amip_albedo_function.yml -> config/model_configs/gpu_amip_albedo_function.yml to reduce confusion with target GPU AMIP runs
• remove scalar indexing in atmos update_field! method for co2 (replace (...)[1] with mean(...))

LGTM, thank you, @juliasloan25. Just a couple of comments. It would be good to increase the t_ends in the long runs, but we can do that later. I've triggered a long run here to see where we get, but we can merge this PR for now.

that longrun is actually for a different branch where I'm trying DYAMOND on GPU, but I started a longrun for this branch here
