Remove the implementation of multiple-profile sampling
The reasons for this change are:
1) this functionality is never used;
2) it's redundant as ThreadProfiler supports periodic sampling.
This change reduces the code complexity and makes the upcoming code
refactoring to support profiling task execution much easier.
