Subject: erts: Make literal_alloc documented and configurable

Except it cannot be disabled and cannot be multi-threaded.

The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only
protected by the literal allocator mutex. We could allow multiple
instances on 64-bit (I think), but what would be the point?
