d6e48195b3 Implement support for WebIDL dictionaries
This commit adds support for generating bindings for dictionaries defined in
WebIDL. Dictionaries are associative arrays which are simply objects in JS with
named keys and some values. In Rust given a dictionary like:

    dictionary Foo {
        long field;
    };

we'll generate a struct like:

    pub struct Foo {
        obj: js_sys::Object,
    }

    impl Foo {
        pub fn new() -> Foo { /* make a blank object */ }

        pub fn field(&mut self, val: i32) -> &mut Self {
            // set the field using `js_sys::Reflect`
        }
    }

    // plus a bunch of AsRef, From, and wasm abi impls

At the same time this adds support for partial dictionaries and dictionary
inheritance. All dictionary fields are optional by default and hence only have
builder-style setters, but dictionaries can also have required fields. Required
fields are exposed as arguments to the `new` constructor.

Closes #241

Should help enable a slew of new bindings as well.

Migrate webidl tests to wasm_bindgen_test (#590)
This commit moves the `webidl/tests` folder to a new `crates/webidl-tests` crate
(to have a test-only build script) and ports them to the `#[wasm_bindgen_test]`
attribute, which should hopefully make testing much speedier for execution!
