LibWeb: Implement the JS host hooks for promises, job callbacks and more

Browse source 
This overrides the JS host hooks to follow the spec for queuing
promises, making/calling job callbacks, unhandled promise rejection
handling and FinalizationRegistry queuing.

This also allows us to drop the on_call_stack_emptied hook in
Document::interpreter().
