perf/probes: Improve probe point syntax of perf-probe
This changes probe point syntax of perf-probe as below
<SRC>[:ABS_LN] [ARGS]
or
<FUNC>[+OFFS|%return][@SRC] [ARGS]
And event name and event group name are automatically
generated based on probe-symbol and offset as below.
perfprobes/SYMBOL_OFFSET[_NUM]
Where SYMBOL is the probing symbol and OFFSET is
the byte offset from the symbol.
