Add --enable-component-model to js ext library

To support graceful migration, we need to support both legacy
wit-bindgen ABI and the latest Component Model ABI at the same time.
This patch does the following:
* Add `--enable-component-model` option to js extconf.rb
* Generate bindings for the latest Component Model ABI
