Upgrade rules_python to 1.7.0

[dabanki]

This is a fork of #27498.

From the comments/open items on that PR, I've:

1. Removed the tests that were called out as not needed.
2. Added manual tag to focus_test to avoid pickup in larger runs until issue with --experimental_enable_skyfocus is resolved.
3. Switched failing test cases from using from bazel_tools.tools.python.runfiles import runfiles to use from python.runfiles import runfiles

There are still a couple failing tests, looking for some guidance on if these can be removed/ignored:

test_source_file_does_not_override_standard_library FAILED: Expected regexp 'I am lib!' not found.

@rickeylev Do the test modifications look okay to you? And do the failing test look important or can they also be removed?

Thanks for taking a look! Do the failing tests look like legitimate issues to you?
