Change profile_provider_unittest to 'console_test_launcher'.

It looks like when someone created the gn_isolate_map.pyl
entry for //chrome/browser/metrics/perf:profile_provider_unittest,
they labelled it as type 'raw', but it looks like this is just
a regular gtest-based test and should've been type
'console_test_launcher'.
