2a252008 - [mlir][tensor] Restrict the verifier for tensor.pack/tensor.unpack (#113108)

[mlir][tensor] Restrict the verifier for tensor.pack/tensor.unpack (#113108) Restricts the verifier for tensor.pack and tensor.unpack Ops so that the following is no longer allowed: ```mlir %c8 = arith.constant 8 : index %0 = tensor.pack %input inner_dims_pos = [0, 1] inner_tiles = [8, %c8] into %output : tensor<?x?xf32> -> tensor<?x?x8x8xf32> ``` Specifically, in line with other Tensor Ops, require: * a dynamic dimensions for each (dynamic) SSA value, * a static dimension for each static size (attribute). In the example above, a static dimension (8) is mixed with a dynamic size (%c8). Note that this is mostly deleting existing code - that's because this change simplifies the logic in verifier.
