[LoongArch] Override TargetLowering::isShuffleMaskLegal
By default, `isShuffleMaskLegal` always returns true, which can result
in the expansion of `BUILD_VECTOR` into a `VECTOR_SHUFFLE` node in
certain situations. Subsequently, the `VECTOR_SHUFFLE` node is expanded
again into a `BUILD_VECTOR`, leading to an infinite loop.
To address this, we always return false, allowing the expansion of
`BUILD_VECTOR` through the stack.
