Fixes missing tier-ing for texture related limits.

- Note the previous roll already removed the expectations for the tests
  in PS1.
- Before this fix, the texture dimension limits were not being tiered.
  After this they should be tiered, but the error tests should still
  pass because
  https://chromium-review.googlesource.com/c/chromium/src/+/5247632
  disables tiering explicitly instead of as a bug for the tests.
