Disable auto-benchmark harness for crates (#8057)

# Description

This disables automatic detection of `#[bench]` and other benchmarks
within the crates. Our benchmarks should all live in `benches`

This fixes a problem with criterion flags and should also reduce the
build requirements for `cargo bench` a bit

Taken from https://github.com/nushell/nushell/pull/7952
