[JSC] Add dumpAndClearSamplingProfilerSamples function
https://bugs.webkit.org/show_bug.cgi?id=259411
rdar://112686960
Reviewed by Justin Michaud.
This patch adds dumpAndClearSamplingProfilerSamples behind a flag, which dumps
sampling profiler data into temp file.
This allows us to automated sampling data collection for benchmarks by calling
this function at the right timing.
We also significantly expand the JSON data generation of SamplingProfiler to
reconstruct enough information from this output.
We also attach display-sampling-profiler-output script as the same to
display-profiler-output. Which can feed the above JSON
and dump sampling profiler output.
