chore: cherry-pick f0a63e1f361f from chromium

Return undefined from UnderlyingSinkBase "type" getter

The "type" attribute of an object passed to the WritableStream
constructor is supposed to return undefined. Add a getter to
UnderlyingSinkBase to ensure it always does.

Add tests to verify that "type" is not inherited from
Object.prototype.type.

Move some methods out-of-line into a new underlying_sink_base.cc file.

Make WritableStreamDefaultController::From() more robust.
