feat(spanner): drop python runtime 3.9 (#17070)
## Description This Pull Request drops support for Python 3.9 in the `google-cloud-spanner` package. This is part of our ongoing effort to modernize the Cloud SDK libraries and remove support for End-of-Life (EOL) Python versions. ## Changes - Removed Python 3.9 from testing configurations and constraints files. - Resolved dependency conflicts arising from dropping support. - Cleaned up obsolete code related to Python 3.9 support.
