  [LV][NFC] Refactor code for extracting first active element (#131118)

Refactor the code to extract the first active element of a
vector in the early exit block, in preparation for PR #130766.
I've replaced the VPInstruction::ExtractFirstActive nodes with
a combination of a new VPInstruction::FirstActiveLane node and
a Instruction::ExtractElement node.
