Inline two constants from CorePlatform

Inlining these constants allow the public api metalava run to depend on
ART's public API rather than the "internal" CorePlatform API, which
prevents picking up unintentional classes (such as annotations) from the
CorePlatform API in the public stubs.

Because these constants get inlined in the API/stubs, and the constants
have been finalized for many years, they can never change. Because they
cannot change, reusing the constant is of limited value. I've added
some comments to point readers to other places the constant is used.
