Subject: [PATCH] [IR][IntrinsicInst] Add VPBinOpIntrinsic

VPIntrinsics with VP_PROPERTY_BINARYOP property should have the ability
to be queried with with VPBinOpIntrinsic::isVPBinOp, similiar to how
intrinsics with the VP_PROPERTY_REDUCTION property can be queried with
VPReductionIntrinsic::isVPReduction.

This will be used in #65706. In that PR the usage of this class is
tested.
