feat[test]: parametrize CI over EVM versions (vyperlang#3842)

this commit parametrizes the github actions rules over evm versions. it
uses the github actions matrix syntax, but because github actions
apparently does not allow additional matrices in the `include` rule, the
additional rules must be written out manually.

misc:
- fix for py-evm logger name
- refactor tests which were previously manually parametrized over evm
  versions
- remove the tox environment for running tests in favor of the gh
  actions script
