SWR compiler warnings `clearing an object of type 'struct ' with no trivial copy-assignment; use assignment or value-initialization instead`

For example the memset in:

INLINE
static void AllocateTessellationData(SWR_CONTEXT* pContext)
{
    /// @TODO - Don't use thread local storage.  Use Worker local storage instead.
    if (gt_pTessellationThreadData == nullptr)
    {
        gt_pTessellationThreadData =
            (TessellationThreadLocalData*)AlignedMalloc(sizeof(TessellationThreadLocalData), 64);
        memset(gt_pTessellationThreadData, 0, sizeof(*gt_pTessellationThreadData));
    }
}

This is blocking enabling -Werror in CI for the meson-gallium job.
