[PATCH v4 0/1] bpf_def.h cleanups

[Marat Khalili <qm2k21@gmail.com>]

The goal of this patch is to clarify the public/private status of the eBPF
definitions and prevent name conflicts. It achieves this by moving the
required public symbols into the public ``rte_bpf.h`` header with a proper
``RTE_`` prefix, and making the remaining ``bpf_def.h`` header private.

v4: reposting verbatim after additional tests involving external apps.

v3:
* Dropped part 2 (renaming macros) as there was no consensus on it.
* Added a release notes entry detailing the API change (bpf_def.h
  becoming private and public symbols moved to rte_bpf.h).

v2:
* Following the AI suggestion renamed `RTE_EBPF_FUNC_MAX_ARGS` to
  `RTE_BPF_FUNC_MAX_ARGS`.
* Rebased on fresh main hoping to overcome the unrelated CI issues.
* Cautiously re-posting without the RFC label.
