In preparation for implementing https://github.com/gpuweb/gpuweb/issues/1604, this change removes the sem::AccessControl node. Instead, the ast::AccessControl::Access enum is now on the sem::StorageTexture class, as well as on sem::Variable. For sem::Variable, the field is set when the variable's type is either a storage buffer or a storage texture. Bug: tint:802 Change-Id: Id479af36b401d067b015027923f4e715f5f69f25 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/51020 Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
