  [MLIR] TosaToLinalg: Prefer to emit identity maps (#123295)

When deciding whether to emit a map like
`#map = affine_map<(d0, d1, d2, d3) -> (0, d1, d2, d3)>` or `#map =
affine_map<(d0, d1, d2, d3) -> (d0, d1, d2, d3)>` for an operand of a
`linalg.generic` when lowering element-wise TOSA ops, prefer the latter
unless broadcasting of the operand is really needed.

This helps later transformations which often require the affine map to
be a projected permuatation.
