eventdev: add experimental tag back for Rx adapter

Add the experimental tag back to the Rx event adapter callback,
the Rx event callback register and the Rx event adapter statistics
retrieval functions due to an API change to be proposed in a
future patch.

This patch also adds the experimental tag to these
function definitions and adds the functions to the EXPERIMENTAL
section of the map file, these were missing previously.

Fixes: 80bdf91dc8ee ("eventdev: promote adapter functions as stable")
