Summary:
These 23 passes in backends/cadence/aot are not Cadence-specific in what
they do, so they move to backends/transforms where any backend can use them:

• Three (FuseCascadedTransposeOrPermuteOps, FuseCascadedViewOps,
  ReplaceNopTransposeOrPermuteWithViewPass) were already empty subclasses of a
  backends/transforms pass, and stay as they are here.
• The other 20 (including RemoveNopAsStridedCopyOpPass) move to
  backends/transforms, one module and target each. The ones that listed
  Cadence's q/dq ops alongside quantized_decomposed's now take those op sets as
  class attributes holding only the standard ops. Cadence keeps each pass under
  its old name as a thin subclass that adds its own ops back, so Cadence's
  behavior is unchanged.
• FuseQuantDequantToRequantizePass needs a requantize op to fuse a pair whose
  qparams differ, and there is no backend-neutral one. The shared pass takes a
  requantize_op (default None) and defaults to allow_requantize=False;
  Cadence sets its op and keeps True.
• permute_pass_utils gains get_overload_packet and get_placeholders, and
  quantize_reorder_utils holds the two op sets the reorder passes share.
