<summary>Changes</summary>
This PR moves vector.insert canonicalizers for DenseElementsAttr (splat and non splat case) to folders. Folders are local, and it's always better to implement a folder than a canonicalizer.
This PR is mostly NFC-ish, because the functionality mostly remains same, but is now run as part of a folder, which is why some tests are changed, because GreedyPatternRewriter tries to fold by default.
