Clean up benchmarks by removing dead code from work_precision_sets

[vidipsingh]

• Removed the entire work_precision_sets folder

Description

This PR removes the benchmarks/work_precision_sets folder, which contained dead code not currently in use by CI or other parts of the system. These files are supposed to be in the validation repository, which is not currently functioning. Removing them helps clean up unused parts of the codebase.

Fixes: #4766

Type of change

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist:

• No style issues: $ pre-commit run (or $ nox -s pre-commit) (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: $ python -m pytest (or $ nox -s tests)
• The documentation builds: $ python -m pytest --doctest-plus src (or $ nox -s doctests)

You can run integration tests, unit tests, and doctests together at once, using $ nox -s quick.

Further checks:

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works

You also need to get rid of the workflow files

I believe you're referring to the work_precision_sets.yml file in the .github/workflows directory. I will go ahead and remove that file.
