Refactor binary op partitioner configs under binary op config class

[mcr229]

Problem

A lot of duplicated code is done for our partitioner configs which take in two inputs (mul, add, sub, etc.) I believe we can refactor these configs: https://github.com/pytorch/executorch/blob/1a9a59b94491f03620dce622fee922c1d2bc1fa7/backends/xnnpack/partition/config/generic_node_configs.py#L100-L107

so that they all inherit from a parent BinaryConfig class. We can then enforce common constraints for these binary configs. This is similar to what we do with the GEMM Config:

https://github.com/pytorch/executorch/blob/1a9a59b94491f03620dce622fee922c1d2bc1fa7/backends/xnnpack/partition/config/gemm_configs.py#L48

Verification

Make sure all existing CI is passing. python -m unittest executorch.backends.xnnpack.test
