Anthony Towns 37b9b67a39 versionbits: Simplify VersionBitsCache API
Replaces State() (which returned ACTIVE/STARTED/etc) with IsActiveAfter()
which just returns a bool, as this was all State was actually used
for. Drops Mask(), which was only used in tests and can be replaced with
`1<<bit`, and also drops StateSinceHeight() and Statistics(), which are
now only used internally for Info().
