[USERENV]

- Fix some DPRINTs;
- Add parameter validation in CreateUserProfileExW;
- Return the directory path of the created profile in CreateUserProfileExW, if the user wants it;
- Add value type validation for RegQueryValueExW calls;
- Use ARRAYSIZE where needed;
- Add parameter validation in GetAllUsersProfileDirectoryA, GetDefaultUserProfileDirectoryA;
- Correctly return error code in GetAllUsersProfileDirectoryW, GetDefaultUserProfileDirectoryW, GetProfilesDirectoryW and GetUserProfileDirectoryW. Should fix the userenv_apitest:GetProfileDirs tests.
