Wasm-bindgen: `#[wasm_bindgen(skip)]` for impls functions

[alexlapa]

Motivation

Add way to skip pub functions in #[wasm_bindgen] impls when generating JS glue.

Proposed Solution

#[wasm_bindgen]
impl Foo {
    #[wasm_bindgen(skip)]
    pub fn bar(&self) -> i32 {
        7
    }
}

Alternatives

Skip pub (crate/self/anything) functions.

You can accomplish this by simply not using #[wasm_bindgen]:

impl Foo {
    pub fn bar(&self) -> i32 {
        7
    }
}

#[wasm_bindgen]
impl Foo {
    // functions that you want to send to JS
}

This works because you can have many impl blocks for a single type.

@Pauan ,

Thanks! Closing then.
