Win32k:

Win32k:
- Add thread information pointer to the user handle entry. This will be useful for checking handles, if the handle is not part of the current thread.
- Add a test to make sure the current process passes the gHandleTable pointer to user32.
- These changes are important for allowing User32 to read-only the handle object information. Not 100% compatible, we need NtUserProcessConnect and CsrClientConnectToServer. Need a full understanding how they both work with User32.
