[REACTOS] Fix misc 64 bit issues (#783) 
* [WIN32K] Fix handle calculation in DbgGdiHTIntegrityCheck
* [NOTEPAD] Fix MSVC warnings
* [PSDK] Simplify *PROC definitions in windef.h
* [VIDEOPRT] Don't try to use NtVdmControl on x64
* [FREELDR] Fix some macros
* [CRT] Make qsort 64 bit compatible
* [NTOS] Use #ifndef _WIN64 instead of #ifdef _M_IX86 around C_ASSERTs
* [FAST486] Fix 64 bit warnings and change DWORD to ULONG, so it can be used in kernel mode
* [APPHELP_APITEST] Fix 64 bit issue
