Add support for meta_struct field in API v4

[manuel-alvarez-alvarez]

What Does This Do

This PR allows adding meta_struct data to spans, the meta_struct is lazy initialized to reduce memory consumption and uses a double locking mechanism to be initialized (same as baggage).

Motivation

The new RASP module requires this new data structure in order to be able to send binary data efficiently to the backend.

Additional Notes

The agent fully supports meta_struct from version v7.35.0 (April 2022).

Sample result of adding a stack to the metra_struct:
