[MLIR] Avoid `vector.extract_strided_slice` when not needed (#115941)
In `staticallyExtractSubvector`, When the extracting slice is the same
as source vector, do not need to emit `vector.extract_strided_slice`.
This fixes the lit test case `@vector_store_i4` in
`mlir\test\Dialect\Vector\vector-emulate-narrow-type.mlir`, where
converting from `vector<8xi4>` to `vector<4xi8>` does not need slice
extraction.
The issue was introduced in #113411 and #115070, CI failure link:
https://buildkite.com/llvm-project/github-pull-requests/builds/118845
This PR does not include a lit test case because it is a fix and the
above mentioned `@vector_store_i4` test actually tests the mechanism.
