Remove all usage of pkg_resources

[scbedd]

We have a base dependency on packaging and we are leaning on that for the modules that are deprecating in setuptools. Resolves #41698

Remaining identified files:

• scripts/devops_tasks/common_tasks.py (used with target path in test_regression.py)
• common/smoketest/dependencies.py
• scripts/devops_tasks/tox_harness.py
• scripts/multiapi_init_gen.py

After pullrequest runs successfully, we should also try a couple runs to be confident in this:

• Nightly core
• Release Core
• Nightly storage

@msyyc hey Yuchao can you please take a look at specifically multiapi_init_gen. I am removing the explicit addition of the azure namespace....I am pretty certain that this should "just work" given PEP 420 implicit namespace packages.

When I used the cheatsheet.md to try generating, I just fail to generate for packages like azure-mgmt-appconfiguration no matter what. Regardless of my change.

Can you please run a quick check for a package you're updating/updated recently and confirm that this change is good to go with this change to scripts/multiapi_init_gen.py?

@scbedd I test your PR locally and it has no impact for sdk generation. As for scripts/multiapi_init_gen.py, it is not used by sdk generation. According to github history, this file was committed 6 years ago and I never change/use it.

Ok. We need to clean up references to this file then. I'll submit a PR and have you review it for correctness. Thank you @msyyc !
