Pull Request resolved: #11480 # Context In this diff we plan on creating the skeleton test framework for dequantization. This is necessary as we need a reference to test our vulkan implementation of the dequantization operator against an existing cpu implementation. This test framework is heavily inspired by [sdpa_test.cpp](https://github.com/pytorch/executorch/blob/main/backends/vulkan/test/op_tests/sdpa_test.cpp). We make use of the [op_dequantize.cpp](https://github.com/pytorch/executorch/blob/main/kernels/quantized/cpu/op_dequantize.cpp) cpu implementation of the `dequantize_per_tensor`, and the `dequantize_per_token` operators. An explanation for the operator is included where the actual vulkan implementation is created in a future diff along this stack. # Changes The main thing in this difference is the creation of a new test framework `dequantize_test.cpp`, and also including it in targets.bzl such that we can properly call the test. As this is inspired by sdpa_test.cpp, we also follow a similar format. First we have forward declarations of the functions that we wish to test against (dequantize_per_tensor, and dequantize_per_token). Then we also have wrappers for the functions without context, and finally wrappers for the ATen implementations of the same operators using the `WRAP_TO_ATEN` macro. We don't need context as this is merely for testing. We also have a utility function to test the quantize arguments that will be used when actually using the vulkan implementation. This utility function is just for a sanity check. ghstack-source-id: 290376489 @exported-using-ghexport Differential Revision: [D76267021](https://our.internmc.facebook.com/intern/diff/D76267021/)
