Fix FastBroadcast extension for v1.0 API

The old 4-arg fast_materialize!(::Static.False, ::DB, dst, bc) signature
no longer exists in FastBroadcast v1.0+. Update to the 2-arg signature
fast_materialize!(dst, bc) which is the correct dispatch point for
custom array types. Bump FastBroadcast compat lower bound to 1.
