need change of set_local_description constructor

[JSmithOner]

Describe the Bug

set_local_description requires a &RtcSessionDescriptionInit to be executed
I can't see the method restartIce neither

basically a lot the current js method and properties don't exist or are incomplete

Steps to Reproduce

look at the rustwasm doc and look a the MDN doc

Expected Behavior

The method should also be callable without argument.

Actual Behavior

the description doesn't get set automatically.

I'm not sure what happened there, but the WebIDL was defined incorrectly in wasm-bindgen, the parameter should be optional: https://www.w3.org/TR/webrtc/#ref-for-dom-peerconnection-setlocaldescription-4.

Unfortunately this can only be fixed in the next breaking change release.

This should be easy to add. Would you like to make a PR?
