[LV] Add tests for more interleave group factors on AArch64 and RISC-V. NFC The plan is to eventually add support for scalably vectorizing these for non-power-of-2 factors, see https://github.com/llvm/llvm-project/pull/139893 Simultaneously, we need to add a test to make sure we don't generate @llvm.vector.[de]interleave3 for AArch64 if we can't lower it (yet)
