  Log Message:
  -----------
  [mlir][SparseTensor] Reject sparse encoding on non-primary types (#209591)

SparseTensorConversion rewrite patterns assume element types are valid
primary types, but the dialect does not actually enforce this
restriction. This change makes it so that sparse tensor encodings
gracefully reject invalid primary types by verifying the encoding.

Closes #202787
Supersedes and closes #208913
