Fix several issues with chpl_gpu.py #26271

Closed jabraham17 closed 2 days ago

jabraham17 commented 3 days ago

This PR fixes several issues I noted while working on https://github.com/chapel-lang/chapel/pull/26267

Most functions were using os.environ.get instead of overrides.get, this meant that gpu config variables could not be read from chplconfig files
Several functions were missing @memoize, this did not effect correctness but could slow down printchplenv
Explicitly setting CHPL_GPU=none and CHPL_LOCALE_MODEL=gpu caused internal errors
