User data is meant to be opaque to the driver. To support this, new API is added to get and set event crypto metadata. The new API, rte_cryptodev_set_session_event_mdata, allows setting event metadata in session private data which is filled inside PMD using a new cryptodev op. This operation can be performed on any of the PMD supported sessions (sym/asym/security). For SW abstraction of event crypto adapter to be used by eventdev library, a new field is added in asymmetric crypto session for now and for symmetric case, current implementation of using userdata is used. Symmetric cases cannot be fixed now, as it will be ABI breakage which will be resolved in DPDK 22.11.
