Re-export wasm-bindgen, js-sys, and event types from web-sys (#642

)

* re-export web_sys for user convenience

* also re-exporting js_sys

* also adding wasm_bindgen because of JsValue

* Only re-export HTML events instead of web-sys

web-sys relies very haevily of feature flags to determine which parts of the API is compiled. Sycamore itself enables a subset of these flags but in many cases, the downstream user will need to add web-sys anyways should they wish to use an API not enabled by Sycamore.

* Remove wasm-bindgen from examples
