Currently, metadata can be set on egress path via mbuf tx_meatadata field
with PKT_TX_METADATA flag and RTE_FLOW_ITEM_TYPE_RX_META matches metadata.

This patch extends the usability.

1) RTE_FLOW_ACTION_TYPE_SET_META

When supporting multiple tables, Tx metadata can also be set by a rule and
matched by another rule. This new action allows metadata to be set as a
result of flow match.

2) Metadata on ingress

There's also need to support metadata on packet Rx. Metadata can be set by
SET_META action and matched by META item like Tx. The final value set by
the action will be delivered to application via mbuf metadata field with
PKT_RX_METADATA ol_flag.

For this purpose, mbuf->tx_metadata is moved as a separate new field and
renamed to 'metadata' to support both Rx and Tx metadata.

For loopback/hairpin packet, metadata set on Rx/Tx may or may not be
propagated to the other path depending on HW capability.
