Add the RTE_LCORE_ prefix to the lcore role enum values in
rte_lcore_role_t
to follow DPDK naming conventions.
- ROLE_RTE -> RTE_LCORE_ROLE_RTE
- ROLE_OFF -> RTE_LCORE_ROLE_OFF
- ROLE_SERVICE -> RTE_LCORE_ROLE_SERVICE
- ROLE_NON_EAL -> RTE_LCORE_ROLE_NON_EAL
Old names are kept as macros aliasing to the new names to preserve
backward compatibility.

The problem with this patch it causes build failures now with abi diff.

We just came back from the Dragon Boat Festival.
I also received this ABI change warning. But I didn't have any good
ideas yet.
Thanks for helping to handle this.
Sorry for the inconvenience.
There is nothing broken from a ABI pov.
This is a limitation in earlier versions of libabigail.
I can't reproduce with libabigail 2.9 (update in progress as I see
2.10 is available now).
I think it was solved in libabigail 2.8
(https://sourceware.org/git/?p=libabigail.git;a=commit;h=6f5f91564bdd).
This seems to solve the problem.
If we want to go with the enum renaming before 26.11, bumping
libabigail to 2.10 in the CI is an option (latest upstream version,
and this is the version in f43 and f44).
I tried it in GHA:
https://github.com/david-marchand/dpdk/actions/runs/27937595115/job/82662953500
I also tested it based on libabigail 2.9.0 version. No any warning.
