[NTOSKRNL/WIN32K/NDK]

- OkToClose procedure (OB_OKAYTOCLOSE_METHOD) returns BOOLEAN, not NTSTATUS
- Check ppi for NULL before dereferencing it in IntWinstaOkToClose (it is NULL, if we do our job of cleaning up the win32 process properly)
- Set the win32 process info to NULL on process cleanup
- Free THREADINFO and PROCESSINFO instead of leaking them
- Set NULL cursor, when the last thread is cleaned up in win32k, so we don't call UserSetCursor() in the process cleanup, when we don't have a THREADINFO anymore. This should hopefully fix a crash of MSVC builds.
- Remove unused UserGetNextHandle function
- Fix some warnings
