76c9b8c49f Python: Expose importNode instead of importModule/importMember
Since predicate name `import` is not allowed, I adopted `importNode` as it sort
of matches what `exprNode` does.

---

Due to only using `importMember` in `os_attr` we previously didn't handle
`import os.path as alias` :|

I did creat a hotfix for this (https://github.com/github/codeql/pull/4446), but
in doing so I realized the core of the problem: We're exposing ourselves to
making these kinds of mistakes by having BOTH importModule and importMember, and
we don't really gain anything from doing this!

We do loose the ability to easily only modeling `from mod import val` and not
`import mod.val`, but I don't think that will ever be relevant.

This change will also make us to recognize some invalid code, for example in

    import os.system as runtime_error

we would now model that `runtime_error` is a reference to the `os.system`
function (although the actual import would result in a runtime error).

Overall these are tradeoffs I'm willing to make, as it does makes things simpler
from a QL modeling point of view, and THAT sounds nice 👍

4bfd55f1af Python: Show problem with os.path modeling
This is not a very good test for showing that we don't handle direct imports,
but it was the best I had available without inventing something new. It's very
fragile, since any of these would propagate taint (due to handling all `join`
calls as if the qualifier was a string):

    ospath_alias.join(ts)
    ospath_alias.join(ts, "foo", "bar")

But this test DOES serve the purpose of illustrating that my fix works :D
