Move all kfunc exports into separate bpf_testmod_kfunc.h header file and include it in tests that need it. We will move all test kfuncs into bpf_testmod in following change, so it's convenient to have declarations in single place. The bpf_testmod_kfunc.h is included by both bpf_testmod and bpf programs that use test kfuncs. As suggested by David, the bpf_testmod_kfunc.h includes vmlinux.h and bpf/bpf_helpers.h for bpf programs build, so the declarations have proper __ksym attribute and we can resolve all the structs. Note in kfunc_call_test_subprog.c we can no longer use the sk_state define from bpf_tcp_helpers.h (because it clashed with vmlinux.h) and we need to address __sk_common.skc_state field directly.
