anv: Don't support ASTC images with modifiers
Before this change, anv_get_image_format_features2 reported support for ASTC formats with any modifier (even those not supported by anv). But, we didn't intend to support that compressed image format with modifiers. With this change, the format feature function reports no support for modifiers on ASTC-formatted images. This prevents the next patch from causing assertion failures due to unsupported modifiers. Fixes: 355f3188438 ("anv: Allow transfer-only linear ASTC images") Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/24120> (cherry picked from commit e50af52e3d9ad7a0a2bdeef5cfea19c973b25aa4)
