perf record: Split -g and --call-graph
Splitting -g and --call-graph for record command, so we could use '-g'
with no option.
The '-g' option now takes NO argument and enables the configured unwind
method, which is currently the frame pointers method.
It will be possible to configure unwind method via config file in
upcoming patches.
All current '-g' arguments is overtaken by --call-graph option.
