Erik Luo 46d815e737 inspector: add lengths for binary data descriptions
This CL adds support for ArrayBuffer and SharedArrayBuffer subtypes for injected
script source. It also adds the byteLength/size to the description of these
objects and for the upcoming "blob" subtype when appropriate.

This is dependent on a DevTools frontend patch to accept these new subtypes:
