st: Pass TextureTiling option from texture to memory obj
If tiling is linear, also adds the corresponding pipe bind flag to the resource template when creating a new resource from the memory object. Modified TexParameteri to update the TextureTiling option only when the texObj is not immutable (before TexStorageMem*DEXT is called to create the texture from external memory). v2: Ensure that memory object is not NULL before setting the TextureTiling option (fixes TexStorage*D). v3: Also add flag PIPE_SHARED to bindings (needed for some gallium drivers). v4: Use PIPE_BIND_LINEAR instead of adding a new PIPE_RESOURCE_FLAG (Marek Olšák) Co-authored-by: Eduardo Lima Mitev <elima@igalia.com> Co-authored-by: Eleni Maria Stea <estea@igalia.com> Co-authored-by: Hyunjun Ko <zzoon@igalia.com> Reviewed-by: Rohan Garg <rohan.garg@collabora.com> Reviewed-by: Rob Clark <robdclark@chromium.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4565>
