Ihor Solodrai	d806f31012	bpf: Migrate bpf_stream_vprintk() to KF_IMPLICIT_ARGS ... Implement bpf_stream_vprintk with an implicit bpf_prog_aux argument, and remote bpf_stream_vprintk_impl from the kernel. Update the selftests to use the new API with implicit argument. bpf_stream_vprintk macro is changed to use the new bpf_stream_vprintk kfunc, and the extern definition of bpf_stream_vprintk_impl is replaced accordingly.

Mykyta Yatsenko	137cc92ffe	bpf: add _impl suffix for bpf_stream_vprintk() kfunc ... Rename bpf_stream_vprintk() to bpf_stream_vprintk_impl(). This makes bpf_stream_vprintk() follow the already established "_impl" suffix-based naming convention for kfuncs with the bpf_prog_aux argument provided by the verifier implicitly. This convention will be taken advantage of with the upcoming KF_IMPLICIT_ARGS feature to preserve backwards compatibility to BPF programs.
