slice of single use rotate -> rotate slice

```

%1258 = stablehlo.slice %1255 [8:12, 6:1526, 0:3056] : (tensor<20x1536x3056xf64>) -> tensor<4x1520x3056xf64> loc(#loc4911)

%2998 = "enzymexla.rotate"(%1258) <{amount = 1 : si32, dimension = 2 : si32}> : (tensor<4x1520x3056xf64>) -> tensor<4x1520x3056xf64> loc(#loc4095)
%3366 = stablehlo.slice %2998 [0:4, 1:1520, 0:3056] : (tensor<4x1520x3056xf64>) -> tensor<4x1519x3056xf64> loc(#loc3026)
```

Start by tracing the stablehlo.slice and enzymexla.rotate operations shown in the issue through the Enzyme-JAX compiler pipeline. Determine where the single-use pattern is handled and verify the intended result by checking the generated IR: the slice should be moved across the rotate as described by the title.
