perf(training): increase default compilation

[cathalobrien]

Description

Following on the rest of this stack, this PR changes the default compilation.

Draft PR while I benchmark different setups to determine a reasonable default config.

I refactored the model yamls and pulled the list of compiled modules into their own files, so you can easily test different levels of compilation

anemoi-training train --config-name=config_n320_gt model/compile=none
anemoi-training train --config-name=config_n320_gt model/compile=medium
anemoi-training train --config-name=config_n320_gt model/compile=max

(it is not a config breaking PR, I followed the existing syntax but refactored into their own files)

currently compile/max.yaml compiles the entire mapper and processor block. compile/medium.yaml maintains the defaults before this PR.
