[VPlan] Fix sentinel assertion when broadcasting invoke results (#210464)

VPTransformState::get broadcasts a scalar value by inserting after the
last scalarized instruction using
std::next(BasicBlock::iterator(LastInst)). When LastInst is a terminator
like invoke, std::next advances past the end of the block, hitting the
!isKnownSentinel() assertion.

Use Instruction::getInsertionPointAfterDef which correctly handles PHIs,
invokes, and regular instructions, matching the pattern already used in
VectorCombine.cpp.

Fixes #210342
