feat[test]: add xfail_strict, clean up setup.cfg (vyperlang#3889)

this commit adds `xfail_strict` to pytest options, and cleans up some
code relating to test and lint setup:
- move pytest coverage-enabling options to CI *only*
- suppress annoying mypy notes
- add `--dist worksteal` to setup.cfg
- pin pytest-xdist due to a regression (pytest-dev/pytest-xdist#1034)
