change key name to be different form native

Current wine has a reading from registry
~~~
        if ( !get_config_key( hkey, appkey, "VideoMemorySize", buffer, size) )
        {
            int TmpVideoMemorySize = atoi(buffer);
            if(TmpVideoMemorySize > 0)
            {
                wined3d_settings.emulated_textureram =
(UINT64)TmpVideoMemorySize *1024*1024;
                TRACE("Use %iMiB = 0x%s bytes for emulated_textureram\n",

~~~
assuming user can change this value. 
It doesn't happen.
The value will change to real value before this reading will occur.
There must be other registry key, for example "EmuVideoMemorySize".
In this case this method is working. The patch attached.
