Michael Layzell 7121551189 Bug 1357829 - Part 2: Use profiler_suspend_sample_thread in the background hang monitor, r=froydnj
This patch uses the profiler_suspend_sample_thread method which was added in
part 1.

With this patch, we no longer manually run code to pause the target thread,
instead using the profiler's provided code to do so. In addition, we no longer
manually walk the stack to collect native stack frames, instead relying on the
profiler's cross-platform stack walking logic.

This helps remove some of the code from ThreadStackHelper which was redundant
with the profiler. Much of the pseudostack code in ThreadStackHelper is also
redundant, and should hopefully be eliminated in a follow-up.
