[ET-VK] Remove test dependency on ATen/native/vulkan/impl

[junpi3]

Stack from ghstack (oldest at bottom):

• [ET-VK] Enable dynamic operator registration #2305
• [ET-VK][EZ] Clean up OperatorRegistry #2304
• -> [ET-VK] Remove test dependency on ATen/native/vulkan/impl #2312

This must land before #2305.

Otherwise, we will have two definitions of the same function signature in executorch/backends/vulkan/runtime/graph/ops/OpUtils.cpp and ATen/native/vulkan/impl/Common.cpp, resulting in a linker error, when building vulkan_compute_api_test_bin:

ld.lld: error: duplicate symbol: at::native::vulkan::adaptive_work_group_size(at::native::vulkan::api::utils::detail::vec<unsigned int, 3u> const&)
>>> defined at Common.cpp:8 (./xplat/caffe2/aten/src/ATen/native/vulkan/impl/Common.cpp:8)

clang-15: error: linker command failed with exit code 1 (use -v to see invocation)

These files are part of the torch_vulkan_ops and vulkan_runtime_graph libraries, respectively.

We resolve the issue by removing the dependency of vulkan_compute_api_test_bin to on torch_vulkan_ops. Unfortunately, this requires copy-pasting more code to VulkanBackend.cpp.
