LibJS: Add Object::may_interfere_with_indexed_property_access() virtual

Browse source 
This function must return true if the object may intercept and customize
access to indexed properties (properties where the property name is a
non-negative integer.)

This will be used to implement fast path optimizations for array-like
accesses in subsequent commits.
