[KERNEL32]

[KERNEL32]
- Added real implementation of SetLastError() (instead of forwarding to NTDLL)
- Implemented BaseSetLastNTError()
- Renamed Basep8BitStringToCachedUnicodeString() to Basep8BitStringToStaticUnicodeString() and sightly changed its implementation
- Fixed implementation of LoadLibraryExA() & DisableThreadLibraryCalls() using those changes
This is matching w2k3 implementation. This is of course a WIP.
