Ihor Solodrai	6e663ffdf7	bpf: Migrate bpf_task_work_schedule_* kfuncs to KF_IMPLICIT_ARGS ... Implement bpf_task_work_schedule_* with an implicit bpf_prog_aux argument, and remove corresponding _impl funcs from the kernel. Update special kfunc checks in the verifier accordingly. Update the selftests to use the new API with implicit argument.

Mykyta Yatsenko	ea0714d61d	bpf:add _impl suffix for bpf_task_work_schedule* kfuncs ... Rename: bpf_task_work_schedule_resume()->bpf_task_work_schedule_resume_impl() bpf_task_work_schedule_signal()->bpf_task_work_schedule_signal_impl() This aligns task work scheduling kfuncs with the established naming scheme 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.

Mykyta Yatsenko	39fd74dfd5	selftests/bpf: BPF task work scheduling tests ... Introducing selftests that check BPF task work scheduling mechanism. Validate that verifier does not accepts incorrect calls to bpf_task_work_schedule kfunc.
