net/mlx5: prepare sub-policy for flow with meter

When a flow has a RSS action, the driver splits
each sub flow finally is configured with
a different HW TIR action.

Any RSS action configured in meter policy may cause
a split in the flow configuration.
To save performance, any TIR action will be configured
in different flow table, so policy can be split to
sub-policies per TIR in the flow creation time.

Create a function to prepare the policy and
its sub-policies for a configured flow with meter.

net/mlx5: support meter creation with policy

Create a meter with the new pre-defined policy.

The following cases to be considered:
1.Add entry match with meter_id in global drop table.
2.For non-termination policy (policy id 0),
  add jump rule to suffix table for green and
  jump rule to drop table for red.
3.Allocate counter per meter in drop table.
4.Allocate meter resource per domain per color.
5.It can work with both ASO and legacy meter HW objects.

net/mlx5: support meter policy operations

MLX5 PMD checks the validation of actions in policy while add
a new meter policy, if pass the validation, allocates the new
policy object from the meter policy indexed memory pool.

It is common to use the same policy for multiple meters.
MLX5 PMD supports two types of policy: termination policy and
no-termination policy.

Implement the next policy operations:
validate:
The driver doesn't support to configure actions in the flow
after the meter action except one case when the meter policy
is configured to do nothing in GREEN\YELLOW and only DROP action
in RED, this special policy is called non-terminated policy
and is handed as a singleton object internally.

For all the terminated policies, the next actions are supported:
GREEN - QUEUE, RSS, PORT_ID, JUMP, DROP, MARK and SET_TAG.
YELLOW - not supported at all -> must be empty.
RED - must include DROP action.

Hence, in ingress case, for example,
QUEUE\RSS\JUMP must be configured as last action for GREEN color.

All the above limitations will be validated.

create:
Validate the policy configuration.
Prepare the related tables and actions.

destroy:
Release the created policy resources.

An application using rte_flow may define a large number of queues
but only use a small subset of them at any one time.

Since querying the status of each queue requires a request/spin/reply

running.
For those queues the statistics will be 0.

acl: fix build with GCC 11

gcc 11 with '-O2' complains about some variables being used without
being initialized:

In function ‘start_flow_avx512x8’,
    inlined from ‘search_trie_avx512x8.constprop’ at acl_run_avx512_common.h:317:
lib/librte_acl/acl_run_avx512_common.h:210:13: warning:
    ‘pdata’ is used uninitialized [-Wuninitialized]
In function ‘search_trie_avx512x8.constprop’:
lib/librte_acl/acl_run_avx512_common.h:314:32: note: ‘pdata’ declared here
...

Indeed, these variables are not explicitly initialized,
but this is done intentionally.
We rely on constant mask value that we pass to start_flow*() functions
as a parameter to mask out uninitialized values.
Note that '-O3' doesn't produce this warning.
Anyway, to support clean build with gcc-11 this patch adds
explicit initialization for these variables.
I checked the output binary: with '-O3' both clang and gcc 10/11
generate no extra code for it.
Also performance test didn't reveal any regressions.
