[BE] shorten the name part 1 (#62402)
Summary:
This should address part of https://github.com/pytorch/pytorch/issues/62357.
1. rename all files 'generated-*' to make it clear, filename will not be in CI workflow name
2. remove all 'pytorch-' in names
3. make sure the build test shell scripts are adopted to new name
Next change should reduce more device related naming
