Move the ConstString pool into a StringPool class and add a non-owning StringPoolRef handle. This is in preparation for having one global and multiple per-Debugger ConstString pool. Strings at the SB API layer will be interned into the appropriate pool. As long as these remain references, this operation is a NOOP.
