[InstCombine] Handle fixed-width results in get_active_lane_mask fold (#185317) ...

The optimization introduced in #183329 incorrectly assumed that any
extraction from a scalable active lane mask used a scalable index. When
the result of a `llvm.vector.extract` is a fixed-width vector, the index
should not be multiplied by vscale.

This PR adds a check to ensure the index is only scaled by VScaleMin
when the return type of the extraction is a scalable vector, not
fixed-width.

Fixes #185271
