Subject: [PATCH] Add WPT console tests

Run the WPT console suite, which checks that console is a namespace
object with the right class string and IDL shape, that it can log
symbols and very large arrays, and that historical members are gone.

41 of 51 subtests pass, including all 28 idlharness subtests. The 10
expected failures are all in console-label-conversion: count,
countReset, time, timeLog and timeEnd come from V8's builtin console,
which doesn't convert object labels with toString() or rethrow errors
thrown by that conversion. helper.js is omitted because discovery
picks it up although it is not a test.
