chore(profiling): test v1 with libdd exporter

[taegyunkim]

A necessary step to remove

1. Legacy pprof/http exporters
2. Stack v1

These test files were removed as they were mostly there to test Legacy pprof exporter code, and we have the same tests in profile-v2 suite, and they don't trigger stack collector at all.

• tests/profiling/collector/test_asyncio.py: AsyncioLockCollector tests
• tests/profiling/collector/test_threading.py: ThreadingLockCollector tests
• tests/profiling/collector/test_threading_asyncio.py: ThreadingLockCollector tests with asyncio

Rest of the test files modified

1. to test with libdatadog profiler exporter if possible
2. to remove references to Recorder class.

I'll follow up with another PR removing legacy pprof/http exporters

In general, seems reasonable. To be transparent, I haven't closely inspected everything since this is a pretty big PR. I basically checked that we have similar coverage either with your modified tests or in the v2 tests for stuff you deleted. Let me know if there's anything you think needs more scrutiny.

Again, this is an interim step before we completely remove stack v1, and v2 is enabled default for a while. So I'll merge this and follow up with removing legacy exporters and v1.

Thanks again for reviews!
