  [RISCV] Disable slideup optimization on the inconsistent element type of EVec and ContainerVT (#159373)

Fixes https://github.com/llvm/llvm-project/issues/159294
The element type of EVecContainerVT and ContainerVT can be different
after promoting integer types.
This patch disables the slideup optimization in that case.
