This is to allow extensions to determine the total length of Javascript blobs.
This cannot AFAIK be done via passing the length in a custom binding, as base::Value does not support int64 a.k.a. 'long long' types.
The total blob length is going to be used in media_galleries_api.cc to construct the SafeMediaMetadataParser in a followup CL. It appears unused in this patch.
