Addressing new review comments from @david-arm & @sdesmalen:

- Removed the `canWidenLoopWithScalableVectors` function, moving the condition to disable scalable vectorization of loops with illegal types into `getMaxLegalScalableVF` instead.
- Removed the changes to add `getSmallestAndWidestTypes` and the `ElementTypesInLoop` list from this patch.
- Improved the CHECK lines in sve-illegal-type.ll.
