Python 3.13 Support

[TimPansino]

Overview

• Add wheels and classifiers for Python 3.13.
  • Update cibuildwheel to use a version with Python 3.13 support.
• Add support for setuptools_scm v7 & v8 for Python 3.13 compatibility.
• Add Python 3.13 to all relevant tox matrices.
  • Add annotated and commented out environments where Python 3.13 is not yet supported by the library. Can be uncommented again to test in the next few weeks as more wheels become available, and should eventually be slotted into the existing matrix line.
• Update C Extensions to work with Python 3.13, and remove Python 2 macros.
• Fix broken tests for agent_unittests in developer mode.
• Fix broken metric across all memcache tests expecting too strict a localhost hostname.

Looks good. Just a couple feedback comments.

[umaannamalai]

Was py313 meant to be added here? This isn't being tested on 3.13 above due to the uvloop dependency.

[TimPansino]

It was added for when we enable the actual tox environment in the future.
