  -----------
  [mlir][tensor] Add test for invalid tensor.unpack + update error msg (#118275)

Adds a new test for invalid `tensor.unpack` operations where the output
rank does not match the expected rank (input rank + num inner tile
sizes). For example:

```mlir
tensor.unpack %output
  inner_dims_pos = [0, 1]
  inner_tiles = [32, 16]
  into %input : tensor<64x32x16xf32> -> tensor<256x128xf32>
```

In addition, updates the corresponding error message to make it more
informative:

BEFORE:
```mlir
error: packed rank must equal unpacked rank + tiling factors}
```

AFTER:
```mlir
error: packed rank != (unpacked rank + num tiling factors), got 3 != 4
```
