IDL compiler: ActivityLog for readonly attributes

Moving on to extended attributes, starting with ActivityLog.

Also rearranged v8_utilities.py, so the actual utilities are at the top, while "shared support for extended attributes" (shared across interfaces, attributes, and operations) is at the bottom, with "which Extended Attribute" clearly marked.
