Subject: [PATCH] feat: regenerate google-cloud-[e-i] packages

This Pull Request drops support for Python <=3.9 in generated
packages. This is part of our ongoing effort to modernize the Cloud
Python SDK libraries and remove support for End-of-Life (EOL) Python
versions.

- Removed Python <=3.9 from testing, configuration, and constraints files.
- Resolved dependency conflicts arising from dropping Python <=3.9 support.
- Cleaned up obsolete code related to Python <=3.9 support.
- Updated select copyright dates
- Updated some autogenerated headings
- Updated some tests to resolve issues discovered during this migration.
