Spec says:
the default entry for a table is always set. It can be set at
compile-time by the P4 programmer - or defaults to NoAction (which is a
no-op) otherwise - and assuming it is not declared as const, can be
modified by the P4Runtime client. Because the default entry is always
set, we do not allow INSERT and DELETE updates on the default entry and
the P4Runtime server must return an INVALID_ARGUMENT error code if the
client attempts one.
With this patch we convert insert or delete operations into modify ones
(unless specified by a driver property, to support non-compliant devices).
For delete, we use the interpreter to suggest a default action that is
the same as the one when the pipeline was originally deployed.
Also, we introduce the capability of synchronizing the device mirror
with the device state.

Different HW platforms have different CPU ports, here we allow using
the same interpreter with multiple platform.

P4 pipeliners are fundamentally different from OpenFlow pipeliners.
It can verify if the flow objective can be translated into a flow that is compatible with the pipeline.
Once verified, it is almost certain the flow can be installed on the switch.
The flow/group subsystem retry mechanism will take care of some rare cases where the flow/group doesn’t get in for the first time.
Therefore, we only fail the objective if there is a translation error in the FabricPipeliner

- Multicast can use the same table as unicast. Merge into one.
- Allow masked destination MAC in classifier table
Note:
- Pipeliner now translates all exact MAC match to masked match with FF:FF:FF:FF:FF:FF mask.
- Interpreter now only uses masked src/dst MAC

There can be multiple next obj waiting for the same flow, i.e. the egress vlan flow.
The key of map is modified to make sure they won't override each other.

Also fix nop action in ingres_port_vlan table not invoking direct
counter.
This allows processing LLDP packets before any SR-related flow rule is
pushed

Remove origin_ether_type from fabric.p4
We can use ether_type from VLAN header since ingress_port_vlan table
always push a VLAN header to the packet if there is no VLAN header.
For configured interface, there exists flow rules to push VLAN.
For ports which not configured (infrastructure ports), the segment routing
application installs a rule which pushed internal VLAN to the packet (4094)

Clone to CPU is available only for packets processed via multicast
groups. Can be changed in the future when implementation for clone
session APIs is available in PI and P4 targets.
Also:
- compile "fabric-full" profile and generate constants from it
- use interpreter to map logical ports to data plane port IDs
