  Convert KeyedLoad indexed interceptor case to a Handler.

  Currently, KeyedLoads on objects with indexed interceptors are handled with a

27f3cc1b9c Require V8 to be explicitly initialized before an Isolate is created 
We also initialize the Isolate on creation.

This should allow for getting rid of the last remaining default isolate
traces. Also, it'll speed up several isolate related operations that no
longer require locks.

Embedders that relied on v8::Isolate to return an uninitialized Isolate
(so they can set ResourceConstraints for example, or set flags that
modify the way the isolate is created) should either do the setup before
creating the isolate, or use the recently added CreateParams to pass e.g.
ResourceConstraints.
