Eliza Weisman 29d85b1adb mock: move layer mock from tracing-subscriber tests (#2369) ...

The `tracing-subscriber` module `tests::support` included functionality
to mock a layer (via the `Layer` trait). This code depends on
some items from `tracing_mock::collector` which should otherwise not be
public.

This change moves the mocking functionality inside `tracing-mock` behind
a feature flag. Allowing the `Expect` enum and `MockHandle::new` from
`tracing_mock::collector` to be made `pub(crate)` instead of `pub`.
Since it's now used from two different modules, the `Expect` enum has
been moved to its own module.

This requires a lot of modifications to imports so that we're not doing
wildcard imports from another crate (i.e. in `tracing-subscriber`
importing wildcards from `tracing-mock`).

This PR is based on @hds' PR #2369, but modified to track renamings. I
also deleted all the doc comments temporarily because updating them was
a lot of work and I need to get a release of `tracing-subscriber` out
first.

Closes: #2359
