add coupler summary table

[juliasloan25]

We want to output a table displaying some information about the current state of the coupler. This table/info should be output to the #coupler-report channel on slack.

The runs will include:

• a CPU atmos-only run
• a GPU atmos-only run
  • config file: config/gpu_configs/gpu_aquaplanet_diagedmf.yml
• a CPU coupled (AMIP) run
• a GPU coupled (AMIP) run

For each of these jobs, we will output the following quantities:

• SYPD
• CPU vs GPU state (max, median, and mean of difference, as is calculated in land
  • update: I'll add these in a separate PR, since this is currently being implemented in debug GPU conservation #614
• allocations at the end of the simulation
  • note that there is no equivalent calculation between CPU and GPU, so these numbers won't be directly comparable

part of #693

To Do

• add config files for the 2 coupled runs
  • based on atmos gpu_aquaplanet_diagedmf.yml
• add config files for the 2 atmos-only runs
  • it might be nice to just access these from ClimaAtmos.jl, but I can't find a cpu run that's equivalent to the gpu config
• set up atmos_driver to run from different config files
• add runs to benchmarks pipeline - ClimaCoupler CPU/GPU Benchmarks (from add GPU AMIP scaling runs #673)
• add in SYPD calculation (from add GPU AMIP scaling runs #673)
• add in allocation printing (from look into allocations #691)
• save these to txt files (as is done with states in debug GPU conservation #614)
• use PrettyTables.jl to create table displaying info read in from these files
• update benchmarks pipeline to send this table to slack channel

To Do in separate issues/PRs

• add atmos-only runs without diagnostic edmf
• add gpu scaling (1, 2, 4 gpus)
• add cpu/gpu state comparison columns
• pass in config file to benchmark script
  • use this to get run names (instead of passing these in), resolution & dt (instead of hardcoding these in table)
• save output as .pdf rather than .txt (use latex backend for PrettyTables)
