doc: make RTE_NEXT_ABI optional in guidelines
Initial process requires oncoming changes described in deprecation notice should be implemented in a RTE_NEXT_ABI gated way. This has been discussed in technical board, and since this can cause a multiple #ifdef blocks in multiple locations of the code, can be confusing specially for the modifications that requires data structure changes. Anyway this was not happening in practice. Making RTE_NEXT_ABI usage more optional based on techboard decision: The intention with using RTE_NEXT_ABI was to provide more information to the user about planned changes, and force developer to think more in coding level. Since RTE_NEXT_ABI become optional, now the preferred way to do this is, if possible, sending changes, described in deprecation notice, as a separate patch and reference it in deprecation notice.

Note that the above process for ABI deprecation should not be undertaken
lightly. ABI stability is extremely important for downstream consumers of the
