[PATCH v4 0/4] add versioned symbols for recently stabilized APIs

[Dariusz Sosnowski <dsosnowski@nvidia.com>]

Main goal of this patchset is to address https://bugs.dpdk.org/show_bug.cgi?id=1957
but it also handles other recently stabilized symbols and has some minor fixes:

- Patch 1 - Fix RTE_VERSION_EXPERIMENTAL_SYMBOL macro on clang.
- Patch 2 - Allow function versioning inside drivers.
- Patch 3 - Version the function symbols stabilized in
  https://git.dpdk.org/dpdk/commit/?id=e8cab133645f5466ef75e511629add43b68a5027
- Patch 4 - Version the rte_flow_dynf_metadata_register() function stabilized in
  https://git.dpdk.org/dpdk/commit/?id=4ee2f5c1cedf9ee7f39afa667f71b07f4004ba5c
  Restore EXPERIMENTAL version on global variable symbols
  rte_flow_dynf_metadata_offs and rte_flow_dynf_metadata_mask.

v4:
- Fixed build with older meson versions.

v3:
- https://inbox.dpdk.org/dev/20260625133311.1299705-1-dsosnowski@nvidia.com/
- Added rebuilding of drivers with -DRTE_BUILD_SHARED_LIB
  whenever function versioning is enabled.

v2:
- https://inbox.dpdk.org/dev/20260624131337.1127323-1-dsosnowski@nvidia.com/
- Drop patches introducing versioning macros for symbol aliases
  and their usage (patch 4 and 5 from v1)
- EXPERIMENTAL version on global variable symbols
  rte_flow_dynf_metadata_offs and rte_flow_dynf_metadata_mask,
  as discussed under v1.
- Change commit title prefix in patch (2) from "drivers" to "build".

v1: https://inbox.dpdk.org/dev/20260623113752.1100072-1-dsosnowski@nvidia.com/
