DeprecationStatus: "active" | "user" | "future" | "obsolete"

The possible statuses that each deprecation can have.

"active" deprecations are currently emitting deprecation warnings. "future" deprecations are not yet active, but will be in the future. "obsolete" deprecations were once active, but no longer are.

The only "user" deprecation is "user-authored", which is used for deprecation warnings coming from user code.
