Retrieve a function PDB symbol correctly from nested blocks

Summary:
This patch fixes a problem with retrieving a function symbol by an
address in a nested block. In the current implementation of
ResolveSymbolContext function it retrieves a symbol with
PDB_SymType::None and then checks if found symbol's tag equals to
PDB_SymType::Function. So, if nested block's symbol was found,
ResolveSymbolContext does not resolve a function.
