This makes it so that v8 stops using the copy of the
endoding library in the template - that is,
third_party/inspector_protocol/lib/encoding_{h,cpp}.template -
and uses the C++ library directly instead. This is done
by having third_party/inspector_protocol/lib/Values_cpp.template
include it, which is configured in the
inspector_protocol_config.json.
