Update enkfgdas_update job resource/env settings (#3047)

Updates for the `enkfgdas_update` job from testing by NCO/GDIT and EMC.
They produce a more stable runtime and bitwise identical outputs to ops.

Add `export OMP_PROC_BIND=true` and update `APRUN_ENKF` to use
`--cpu-bind core` instead of `--cpu-bind depth` in WCOSS2.env. 
Also, adjust npe (280) and thread (16) values.

NCO requests that we include these updates in the GFSv16.3.21 package.
