[DispatchCreation] Register enum literals for parsing data-tiling hint op types (#24711)

The CLI option that lists op families eligible for data-tiling
annotation takes `EncodingOpType` enum values, but no `cl::values` were
registered for it. Hence, passing a keyword such as `convolution` on the
command line to
`--iree-dispatch-creation-experimental-set-data-tiling-ops` failed to
parse. Register the literals (`matmul`, `scaled_matmul`, `convolution`)
so the option is actually usable from `iree-compile`.
