#2651 improve tests arguments passing

- use `HARNESS_OPTIONS` to pass formatter and jobs number (still can't pass `--merge`, see Perl-Toolchain-Gang/Test-Harness#117)
- use `HARNESS_PERL_SWITCHES` instead of `PassEnv` plugin

We need such approach to be able to use any frontend, besides `prove`, e.g. `make test`

Fixes #2651
