We have ./miri many-seeds for our own development and testing purposes, but this could also be useful for end-users. I am imagining something like cargo miri --many-seeds=0..256 test ... or so, which would run the test 256 times with different seeds.

cargo miri: add support for '--many-seeds'

to run the program / tests many times with different seeds: `cargo miri run --many-seeds` / `cargo miri test --many-seeds`.

`@rust-lang/miri` any opinion on the flag name here? Should it be `-Zmiri-many-seeds` or is `--many-seeds` fine?

Fixes rust-lang/miri#3546
