Subject: [PATCH v2 0/2] tracing/probes: allow no event name input when create group

take kprobe event as example, when create a group of events,
p[:[GRP/]EVENT] [MOD:]KSYM[+OFFS]|KADDR [FETCHARGS],
according to this format, we must input EVENT name,

this change allow only GRP/ input, EVENT name auto generate from KSYM,
p[:[GRP/][EVENT]] [MOD:]KSYM[+OFFS]|KADDR [FETCHARGS]

siliar change apply to eprobe and uprobe.

V1: https://lore.kernel.org/lkml/1651397651-30454-1-git-send-email-quic_linyyuan@quicinc.com/T/#m33b0665941d9caeeb118afa84db4016321cea9a6
V2: fix remove comment in V1 patch1,
    remove v1 patch2 as it is NACK.
