Add error messages on pdb Open function

Browse Source 
This implements the error messages from
https://docs.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/idiadatasource-loaddataforexe?view=vs-2022
and
https://docs.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/idiadatasource-loaddatafrompdb?view=vs-2022
instead of having just a generic error message.
