Update the crates.io publishing scripts (#580)

* Fix fuzz target compilation.

* Bump version to 0.7.0

* Temporarily disable fuzz tests

Temporarily disable fuzz tests until https://github.com/bytecodealliance/cranelift/issues/1216 is resolved.

* Fix publish-all.sh to not modify the witx crate.

* Remove the "publish = false" attribute from Lightbeam.

* Add a README.md for wasmtime-interface-types.

* Remove the "rust" category.

This fixes the following warning:

warning: the following are not valid category slugs and were ignored: rust. Please see https://crates.io/category_slugs for the list of all category slugs.

* Mark wasmtime-cli as "publish = false".

* Sort the publishing rules in topological order.

Also, publish nightly-only crates with cargo +nightly.
