Support more internal utils under Ravenwood.

Tests for these internal utils are local within the frameworks/base/
repo, instead of in CTS.

To help future-proof, bring the entire utils/* test directory by
default into the Ravenwood suites, and give developers the way to
easily opt-out with @IgnoreUnderRavenwood at the class level.
