Data-tiling encodings: take the element types out of the enums. (iree…

This has been discussed for a while: ever since iree-org#14336 made encodings a
data structure, it was an odd remnant that we were still encoding the
element types tuple in the user enum. This was cumbersome, and
resurfaced in every design discussion as it looked like something that
wasn't scaling with new data types. Concretely, this is good to fix
ahead of adding `i16xi16` and `i16xi4` data-tiling support (iree-org#15158).
