[mlir][MemRef] Simplify extract_strided_metadata(reinterpret_cast)

[mlir][MemRef] Simplify extract_strided_metadata(reinterpret_cast)

This patch adds a pattern to simplify
```
base, offset, sizes, strides =
  extract_strided_metadata(
    reinterpret_cast(src, srcOffset, srcSizes, srcStrides))
```

Into
```
base, baseOffset, ... = extract_strided_metadata(src)
offset = srcOffset
sizes = srcSizes
strides = srcStrides
```

Note: Reinterpret_cast with unranked sources are not simplified since
they cannot feed extract_strided_metadata operations.
