[20.11,v2] stack: remove experimental tag from API

  The stack library was first released in 19.05, and its interfaces have been
stable since their initial introduction. This commit promotes the full
interface to stable, starting with the 20.11 major version.

v2:
- Added 20.11 tag, will set patch status to 'Deferred' so it is skipped
  for the 20.08 development period.
- Added release notes announcement. release_20_11.rst doesn't exist yet,
  so I made the change to release_20_08.rst then edited the filename
  directly in the patch. This will not apply cleanly.
- Changed rte_stack_version.map version to DPDK_21.

I think you did it right.

I would move this to the API changes section, as proposed by Thomas before.

There is a little conflict here that git-pw/git-am seems to silently skip...

Otherwise, lgtm.
