    gsk: Fix build on Visual Studio
    
    One cannot use #if...#endif within macro calls in Visual Studio and
    possibly other compilers, and there are more uses of VLAs that need to be
    replaced with g_newa().
    
    There were also checks for the clip type in gskvulkanrenderpass.c which
    were possibly not done right (using the address of the type value to check
    for a type value), which triggered errors as one is attempting to compare
    a pointer type to an enum/int type.
