Add feature detector of kernel-side arg:ctx (__arg_ctx) tag support. If this is detected, libbpf will avoid doing any __arg_ctx-related BTF rewriting and checks in favor of letting kernel handle this completely. test_global_funcs/ctx_arg_rewrite subtest is adjusted to do the same feature detection (albeit in much simpler, though round-about and inefficient, way), and skip the tests. This is done to still be able to execute this test on older kernels (like in libbpf CI). Note, BPF token series ([0]) does a major refactor and code moving of libbpf-internal feature detection "framework", so to avoid unnecessary conflicts we keep newly added feature detection stand-alone with ad-hoc result caching. Once things settle, there will be a small follow up to re-integrate everything back and move code into its final place in newly-added (by BPF token series) features.c file.
