  [AArch64] Consider StreamingSVE in shouldExpandGetActiveLaneMask (#144722)

If StreamingSVE is available, we may be able to lower the intrinsic
to the GET_ACTIVE_LANE_MASK node instead of expanding it.
Also adds the node to addTypeForFixedLengthSVE to ensure we lower
to the SVE instruction when useSVEForFixedLengthVectors is true.
