  [IR] Vector extract last active element intrinsic (#113587)

As discussed in #112738, it may be better to have an intrinsic to represent vector element extracts based on mask bits. This intrinsic is for the case of extracting the last active element, if any, or a default value if the mask is all-false.

The target-agnostic SelectionDAG lowering is similar to the IR in #106560.
