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.
