  Small build time improvement for WebPreferences

Reviewed by Elliott Williams.

WebPreferences.h currently includes <WebCore/LibWebRTCProvider.h>, which is costly to parse.

By adding a small helper function to WebPreferencesDefaultValues, we can avoid requiring users
of WebPreferences.h from including this header. This saves about 9 seconds of parsing time
on an M1 Pro.

(WebKit::defaultPeerConnectionEnabledAvailable): Added.
