feat: findRelatedTests flag, to run only changed tests

[sheremet-va]

Related: #280

CAC allows passing array as an argument only if you repeat option, like:

vitest --findRelatedTests src/timeout.ts --findRelatedTests src/mockedA.ts

I personally think jest's way (using space as separator) is more convinient

We could use comma and split it ourselves

Still not ideal. I like space and think we would need it in the future because */** syntax returns files separated by space. It's just natural.

Also I think most of the people using this feature have it configured the same for eslint and other tools that support passing files, and It wouldn't be convenient to redo the files array just for vitest.

idk, won't that have an ambiguous issue to distinguish from options args or command args?

In what way? Maybe it's harder for parser, but I think it looks more native to the human eye, no?

Maybe we should ask in Discord

Should placing options before arguments be allowed tho?

Yargs for example can parse array of options

I think we should merge this PR as it is and discuss this separately, since it will involve cli package and maybe no one will complain 😄
