Migrate four more shared objects to use SharedObjectKind

[CraigMacomber]

Description

These are all internal or alpha, and still export the classes in case something actually needs them.

Breaking Changes

Users of SharedNumberSequence, SharedObjectSequence, SparseMatrix or ConsensusQueue will need to update their code to use the *Class exports if they have a dependency on something static from class thats not on the shared object kind, like its constructor.
