Fix C# wrappers FxCop warning CA2002 in SWIGPendingException
Fixes two warnings in each wrapper:
warning : CA2002 : Microsoft.Reliability : 'examplePINVOKE.SWIGPendingException.Retrieve()' locks on a reference of type 'Type'. Replace this with a lock against an object with strong-identity.
warning : CA2002 : Microsoft.Reliability : 'examplePINVOKE.SWIGPendingException.Set(Exception)' locks on a reference of type 'Type'. Replace this with a lock against an object with strong-identity.
Use lock statement advice not to use typeof for locks, see
https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/lock-statement
