Update on "[ET-VK] Enable dynamic operator registration"

This change follows
1. in the footsteps of #2222 for static initialization and
2. the popular `TorchLibraryImpl` for wrapping with macros.

Contributors can now write their operator and register them within the same file using `REGISTER_OPERATORS` + `VK_REGISTER_OP()`, as shown in `Arithmetic.h/cpp`.

Typically in Linux/Android C++ environments, the symbols corresponding to `OperatorRegisterInit` static instances are discarded since they aren't used for anything other than static initialization. Hence, we need to `link_whole = True` for the `vulkan_graph_runtime` library.

We update our Compute API tests to verify we can go through `OperatorRegistry` with proper static initialization.
