feat(tvix/eval): allow to disable warnings r/5117

The nix_tests test suite produces lots of warnings.  We can't fix
these, since they are kept in sync with upstream, so there's little
point in cluttering up the console with them every time the tests
are run.

Let's add a clap flag "warnings" and TVIX_WARNINGS environment
variable.  The default is "true".  The test runner overrides this
default and mutes the warnings.
