Separates profile 2 into 2 profiles 2 and 3

Separates HBD profile int two profiles (2 and 3) consistent with the
highbitdepth branch. This patch is ported from the original highbitdepth
branch patch: https://gerrit.chromium.org/gerrit/#/c/70460/

Two of the invalid file tests needed to be updated.
