This adds the build target inspector_protocol_parser_test, which depends
on several more inspector protocol related targets. The resulting
gtest executable runs, but has failures that have to be fixed.

GN build configuration will follow.

A copy of v8-inspector/js_protocol.json has been included to be able to
use it before the actual migration.
