Andreas Kling b5babda288 LibWeb: Cache UniversalGlobalScopeMixin pointer on ESO 
Avoid expensive cross-hierarchy dynamic_cast from JS::Object to
UniversalGlobalScopeMixin on every microtask checkpoint.

Since UniversalGlobalScopeMixin is not in the JS::Object
inheritance chain, as<UniversalGlobalScopeMixin>(JS::Object&)
falls through to dynamic_cast, which is very costly. Profiling
showed this taking ~14% of total CPU time.

Add EnvironmentSettingsObject::universal_global_scope() backed
by a pointer cached eagerly during initialization.
