Benedikt Meurer 7e2f11082b [inspector] Fix crash due to misuse of embedder fields. 
The contract between V8 and Blink is that embedder fields belong to
Blink, at least when the object has two or more of them. Now we had 2-3
embedder fields used by the debug proxies and that was confusing Blink,
since it expects the first slot to hold an aligned pointer in that case
and we had a HeapObject reference stored there.

This is a quickfix, which avoids internal fields completely for the
context extension proxy (using interceptors on the prototype instead)
and changes the named proxies to store the name table under a private
symbol instead of using a second internal field.

A proper but way more involved fix is to introduce a proper instance
type here and use space in the header instead of misusing embedder
fields.
