Introduce NativeRawSymbol for PDB reading.

This is a stub for a new concrete implementation of IPDBRawSymbol.
Nothing uses this uses this implementation yet.  My plan is to
locally switch lldb-pdbdump from the DIA reader to the Native one
and flesh out the implementations of these method stubs in the order
they're needed.
