`wasm-tools print --skeleton` with no core modules

[rylev]

Often times when debugging, I find myself looking at the pieces of a component that are related directly to the component model and wishing to skip over core modules. This would be particularly helpful when core module functions have names which contain substrings of component extern items as simple string searches often turn up component related items along with core module functions.

Would it make sense to provide an option to elide core modules with something like (core module (;0;) ...)?
