In order to remove the kMaxBindingsPerGroup limit in Dawn, some static ityp::arrays need to be made dynamically sized. This CL adds ityp::vector wrapping std::vector. This CL also fixes the assumption that ityp::stack_vec iterators are pointers Bug: dawn:442, dawn:443 Change-Id: I8698cbba3ea80ac063ab918a77f223c527720d08 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/24480 Commit-Queue: Austin Eng <enga@chromium.org> Reviewed-by: Stephen White <senorblanco@chromium.org>
