Windows,JNI,logging: improve error messages

In this commit:
- introduce the MakeErrorMessage function, which
  creates a structured error message with file
  and line information of the error's origin
- update all error messages in the Windows JNI
  library
- simplify GetLastErrorMessage to just convert an
  error code to string, without prepending a cause
