[LoongArch] Add demanded bits support for [X]VMSKLTZ (#143528)
This patch adds a DAG combine hook for the [X]VMSKLTZ nodes to simplify
their input when possible. It also implements target-specific logic in
SimplifyDemandedBitsForTargetNode to optimize away unnecessary
computations when only a subset of the sign bits in the vector results
is actually used.
