This allows the ability to call IPDBSession::getGlobalScope with a NativeSession and
to then query it for some basic fields from the PDB's InfoStream.
Note that the symbols now have non-const references back to the Session so that
NativeRawSymbol can access the PDBFile through the Session.

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.
