Matt Clay 4fb485a155 Improve ansible-test environment checking between tests. (#46459)
* Add unified diff output to environment validation.

This makes it easier to see where the environment changed.

* Compare Python interpreters by version to pip shebangs.

This helps expose cases where pip executables use a different
Python interpreter than is expected.

* Query `pip.__version__` instead of using `pip --version`.

This is a much faster way to query the pip version. It also more
closely matches how we invoke pip within ansible-test.

* Remove redundant environment scan between tests.

This reuses the environment scan from the end of the previous test
as the basis for comparison during the next test.
