util+treewide: container_of() cleanup

Replace mesa's slightly different container_of() with one more aligned
to the linux kernel's version which takes a type as the 2nd param.  This
avoids warnings like:

  freedreno_context.c:396:44: warning: variable 'batch' is uninitialized when used within its own initialization [-Wuninitialized]

At the same time, we can add additional build-time type-checking asserts
