Ladybird+LibWeb: Add optional IDL call tracing

Browse Source 
When launched with the new --enable-idl-tracing option, we now log
every call to web platform APIs declared via IDL, along with the
arguments passed.

This can be very helpful when trying to figure out what a site is
doing, especially if it's not doing what you'd expect.
