libservo: Create a WebViewBuilder class to construct WebViews (#36483)

Browse source 
This exposes a new method of creating `WebView`s using the Rust builder
pattern. This will be more important as we add more kinds of
configuration options for `WebView` such as size and HiDPI scaling.

Testing: The API currently doesn't have tests, but functionality is
ensured by the fact that servoshell is the test harness.
