[SLP]Fix PR61554: use of missing vectorized value in buildvector nodes.

If the buildvector node matches the vector node, it reuse the vector
value from this vector node, but its VectorizedValue field is not
updated. Need to update this field to avoid misses during the analysis
of the reused gather/buildvector nodes.
