[llvm] [TTI] Remove getVPMemoryOpCost. NFC (PR #160838)

[Luke Lau via llvm-commits]

https://github.com/lukel97 created https://github.com/llvm/llvm-project/pull/160838

No target implements this and nothing calls it. The cost of vp.load/store/gather/scatter etc. are handled by BasicTTIImpl::getIntrinsicInstrCost which forwards it onto the appropriate TTI::getMemoryOpCost/getGatherScatterOpCost etc.
