Move dependencies from requirements.txt to an optional packaging extra

[kkraus14]

Description

Moves packages needed for testing to an optional dependency group and updates CI and docs to use said optional dependency group. Additionally removes some unused dependencies and specifies versions where they weren't previously specified but were required.

Looks good to me, but just to point out our options:

• This could be left commented out (status quo), with

# Uncomment to generate MINIMAL_NVVMIR_BITCODE_STATIC for test_nvvm.py (see PR #443).

• If we choose to make this an unconditional test dependency: I'll work on a follow-on PR to simplify the logic in cuda_bindings/tests/test_nvvm.py. I believe we can then remove the MINIMAL_NVVMIR_BITCODE_STATIC dictionary entirely.

This is something I wanted to discuss. I could pull it out into a separate optional dependency group of something like test-nvvm or something of the likes. One of my motivations for uncommenting it was to have it start being tested in CI.

My vote, based on the quick experiment below (pip install llvmlite takes less than 1 second):

• Make llvmlite an unconditional test dependency, as you have it right now.
• I'll do the follow-on PR (quickly, should be easy to squeeze in).
