Add ThreadFilterBenchmark

[zhengyu123]

What does this PR do?:
This benchmark is extracted from @r1viollet 's PR#209

Motivation:
I would like to merge this benchmark separately, so we can use it to experiment various ideas for improving thread filter.

Additional Notes:

How to test the change?:

For Datadog employees:

• If this PR touches code that signs or publishes builds or packages, or handles
  credentials of any kind, I've requested a review from @DataDog/security-design-and-guidance.
• This PR doesn't touch any of that.
• JIRA: PROF-11548

Ok, let's start with this.
My only objection is that this is, technically, not a microbenchmark. The measured code does a lot of things so it will be highly susceptible to noise.
