[VPlan] Restrict hoisting of broadcast operations using VPDominatorTree (#117138)
This patch restricts broadcast operations from being hoisted to the vector
preheader unless the basic block that defines the broadcasted value properly
dominates the vector preheader.
This prevents potential use-before-definition issues when the broadcasted
value is defined within the plan. VPDominatorTree is used to confirm this
restriction while still allowing safe hoisting for broadcasted values defined
outside the plan.
