**What does this PR do?** This PR updates the C/C++ reference implementation to introduce top-level `ProcessContext` message that wraps the previous `Resource` message. **Motivation:** Having a top-level `ProcessContext` message gives us more flexibility to evolve the `ProcessContext` in the future without directly depending on `Resource`, as well as to introduce attributes that are not considered part of the `Resource` and that may need to be updated from time to time. **Additional Notes:** N/A **How to test the change?** The built-in decoder and `otel_process_ctx_dump.sh` have been updated to match.

Nit: Maybe if you do additional modifications in the future to address OTEP comments, add 1-2 attributes in extra_attributes to demonstrate non-resource attribute handling.

Yeap, sounds good! I need to make a few tweaks to support the thread context which is an extra_attribute so I'll include that as well.

What does this PR do?
This PR updates the C/C++ reference implementation to introduce top-level
ProcessContextmessage that wraps the previousResourcemessage.Motivation:
Having a top-level
ProcessContextmessage gives us more flexibility to evolve theProcessContextin the future without directly depending onResource, as well as to introduce attributes that are not considered part of theResourceand that may need tobe updated from time to time.
Additional Notes:
Currently every attribute provided to the library ends up inside the resource; I plan to later extend this to allow attributes to be provided that end up inside the
extra_attributes.How to test the change?
The built-in decoder and
otel_process_ctx_dump.shhave been updated to match.
