[mlir][MemRef] Change the anchor point of a reshapeLikeOp pattern
Essentially, this patches changes the anchor point of the
`extract_strided_metadata(reshapeLikeOp)` pattern from
`extract_strided_metadata` to `reshapeLikeOp`.
In details, this means that instead of replacing:
```
base, offset, sizes, strides =
extract_strided_metadata(reshapeLikeOp(src))
```
With
```
base, offset = extract_strided_metadata(src)
sizes = <some math>
strides = <some math>
```
We replace only the reshapeLikeOp part and connect it back with a
reinterpret_cast:
```
val = reshapeLikeOp(src)
```
=>
```
base, offset, ... = extract_strided_metadata(src)
sizes = <some math>
strides = <some math>
val = reinterpret_cast base, offset, sizes, strides
