[X86][Costmodel] Load/store i32/f32 Stride=3 VF=16 interleaving costs

The only sched models that for cpu's that support avx2
but not avx512 are: haswell, broadwell, skylake, zen1-3

For load we have:
https://godbolt.org/z/5fqrh4qqo - for intels `Block RThroughput: =14.0`; for ryzens, `Block RThroughput: <=12.0`
So pick cost of `14`.

For store we have:
https://godbolt.org/z/5fqrh4qqo - for intels `Block RThroughput: =22.0`; for ryzens, `Block RThroughput: <=16.0`
So pick cost of `22`.

I'm directly using the shuffling asm the llc produced,
without any manual fixups that may be needed
to ensure sequential execution.
