net: prestera: acl: add multi-chain support offload

Add support of rule offloading added to the non-zero index chain,
which was previously forbidden. Also, goto action is offloaded
allowing to jump for processing of desired chain.

Note that only implicit chain 0 is bound to the device port(s) for
processing. The rest of chains have to be jumped by actions.
