selftests/bpf: Add unit tests for global functions
test_global_func[12] - check 512 stack limit.
test_global_func[34] - check 8 frame call chain limit.
test_global_func5 - check that non-ctx pointer cannot be passed into
a function that expects context.
test_global_func6 - check that ctx pointer is unmodified.
test_global_func7 - check that global function returns scalar.
