Improve resource loading by ~3x

Bug: 22392651

ColorStateLists were never cached because the lazy-create
of the constant state had a typo.

Resource caching in general was broken because ThemeKey did not
clone the hash code, so all keys in the cache had a hashCode
of 0 which did not match the real, uncloned ThemeKeys hash code
so the binary search in ArrayMap based off of hash code was failing.
