What does this PR do?

  • Introduce a new profiling collector responsible for gathering system info data and refreshing it before each upload.
  • The system info gets added to the profile through a new field added by [PROF-8037] System info support for pprof profiles libdatadog#289
  • Backend and frontend support enables showing this info along with derived uptime from info.application.start_time:

Motivation:

  • Feature parity with Java in terms of observability into system/runtime/application/profiler settings.

Additional Notes:
This requires using a new release of libdatadog with DataDog/libdatadog#289 merged

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.

Unsure? Have a question? Request a review!

**What does this PR do?**

This PR upgrades dd-trace-rb to use libdatadog 6. The highlight of
this release are memory footprint improvements when using the
profiling timeline feature.

There was a small breaking API change -- the addition of the
`info` parameter in `ddog_prof_Exporter_Request_build`, which will
be used in #3357 but for this PR I only passed in a `NULL`.

**Motivation:**

Pick up the timeline memory improvements.

**Additional Notes:**

N/A

**How to test the change?**

Our existing test coverage includes libdatadog testing, so a green
CI is good here :)
