perf tools: Add a general option to enable raw sample records

While we can enable the perf sample records per tracepoint
counter, we may also want to enable this option for every
tracepoint counters to open, so that we don't need to add a
:record flag for all of them.

Add the -R, --raw-samples options for this purpose.
