X-link: https://github.com/pytorch/executorch/pull/5720
For smaller models the overhead of profiling ops might be prohibitively large (distorting the inference execution time significantly) so we provide users an option to disable op profiling and essentially only profile the important events such as inference execution time.
To disable operator profiling users need to do:
```
etdump_gen.set_event_tracer_profiling_level(executorch::runtime::EventTracerProfilingLevel::kNoOperatorProfiling);
```
Test Plan: Added test case.

Summary:
This diff adds support in the ExecuTorch codegen layer to log the outputs of kernels to event_tracer. It does this by calling the `event_tracer_log_evalue` API.
When the `ET_EVENT_TRACER_ENABLED` flag is disabled this is essentially a no-op and will add no overhead.

Summary: Currently we rely on root operator, but we also need to check for et_kernel_metadata for used specialized kernels.

Summary:
keys and change codegen to take ETKernelIndex
We are adding support for dtype and dim order specialized kernel registration. This requires us to reorganize `BackendIndex` (which is a `Dict[DispatchKey, Dict[OperatorName, BackendMetadata]]`) to be `Dict[OperatorName, Dict[ETKernelKey, BackendMetadata]]`. This PR adds new data structures in order to support this change:
* `ETKernelKey` to retrieve a certain kernel from the registry.
* `ETKernelIndex`, the dictionary from operator name to kernel key to kernel mapping.
Note that the codegen logic is not changed yet, we need subsequent diffs to actually generate code for different kernel keys.

Summary:
In ATen mode, we add the RuntimeContext arg, so we have something like
```
TORCH_API inline at::Tensor & gelu_outf(torch::executor::RuntimeContext & context, const at::Tensor & self, c10::string_view approximate, at::Tensor & out) {
return at::gelu_outf(self, approximate, out);
}
```
and user can use `<namespace like aten>::gelu_outf` and we will automatically dispatch the registered function in aten kernel using `at::gelu_outf` (dispatched by ATen/Functions.h header)
In optimized kernel tests, we can now automatically handle between aten kernel and optimized kernel.
The implication is that the test must depend on the correctness of codegen; an error in codegen can break the kernel tests.
