Nico Flaig fa898bb319 chore: restructure tests (#7793)
Follow up to https://github.com/ChainSafe/lodestar/pull/7610 with a few
restructuring suggestions, see comments below for detailed changes,
revives constants tests we are no longer running in CI and makes each
package executable separately again, ie. `cd packages/<package-name>`
into `yarn test:unit` works for all packages again.

One major change is that unit tests default should be written with
`mainnet` preset in mind as I noticed that makes a lot more sense for a
bunch of existing tests, eg. we have tests that depend on external
fixtures, like api spec tests for events and those are not compatible
with `minimal` preset. Also there doesn't seem to be much downside in
most cases for unit tests to use `mainnet` preset as it does not run
through all the epoch, like for example a e2e or sim test does. So
overall, it allows us to use mainnet fixtures / more "real world" data
which seems better with little to no downside.


Time comparison running unit tests on `unstable` vs. this branch

There is just a difference of 2 seconds (might be a fluke) in a 6 minute
run, this seems acceptable to me considering the benefits of using
`mainnet` preset noted above.
