This implements `DoLoadImage` and `UnloadImage` in the Windows platform plugin modelled after the POSIX platform plugin. This was previously unimplemented and resulted in a difficult to decipher error without any logging. This implementation is intended to support enables the use of LLDB's Swift REPL on Windows. Paths which are added to the library search path are persistent and applied to all subsequent loads. This can be adjusted in the future by storing all the cookies and restoring the path prior to returning from the helper. However, the dynamic path count makes this a bit more challenging.
