ebpf_program_execute_test_run should invoke via NMR contract

The current ebpf_program_execute_test_run path bypasses the NMR contract and invokes the program directly. To better measure the actual performance of a BPF program, this path should instead invoke BPF programs via the NMR client dispatch table.

Start by locating the ebpf_program_execute_test_run path and tracing how it currently invokes the program. Compare that path with the NMR client dispatch table; done means BPF programs are invoked through the NMR contract so the performance measurement reflects that dispatch path.
