Put a lock around cargo build invocations for plugin tests (#8333)
I think this _might_ fix the issues we've been seeing with plugin tests.

In a nutshell, the plugin tests run `cargo build` to ensure that plugins
have been built:
f6ca62384e/crates/nu-test-support/src/commands.rs (L6)

This PR adds a mutex to ensure that we're never running `cargo build`
concurrently. It also uses an atomic bool to signal when plugins have
already been built, so we can avoid invoking `cargo build` multiple
times unnecessarily.

I can't be certain yet, but I'm guessing the macOS CI problems we've
been seeing come from plugin tests clobbering each other (something
like: test 1 builds the `foo` plugin, then test2 invokes `cargo build`
again and deletes the `foo` plugin from disk).
