ipcz: Ref counted fragments

Introduces RefCountedFragment and FragmentRef<T> as helpers to support
ref-counted objects living in shared memory fragments, as allocated
via NodeLinkMemory.

Also introduces some builtin BlockAllocators to each NodeLinkMemory's
primary buffer.

This change lays the ground work for dynamic allocation of managed state
objects between each connected pair of Routers.
