Actually record identifiable WebGL parameters that are integers.

The instrumentation of GetIntParameter() was accidentally omitted from
http://crrev.com/c/2364953.

I also replaced the uses of IdentifiableTokenBuilder.AddToken() to the
preferred method, AddValue(), where appropriate in the same file.
