[DebugInfo] Add a new method IPDBSession::findLineNumbersBySectOffset
Summary:
Some PDB symbols do not have a valid VA or RVA but have Addr by Section and Offset. For example, a variable in thread-local storage has the following properties:
get_addressOffset: 0
get_addressSection: 5
get_lexicalParentId: 2
get_name: g_tls
get_symIndexId: 12
get_typeId: 4
get_dataKind: 6
get_symTag: 7
get_locationType: 2
This change provides a new method to locate line numbers by Section and Offset from those symbols.
