net/mlx5: fix meta register conversion for extensive mode

Register C is used in the extensive metadata mode number 1 and its
width can vary from 0 to 32 bits depending on the kernel usage of it.

There are several issues associated with this mode (dv_xmeta_en=1):
1. The metadata setting assumes that the width is always 16 bits,
which is the most common case in this mode. Use the proper mask.
2. The same is true for the modify_field Flow API. 16-bits width
is hardcoded for dv_xmeta_en=1. Switch to the register C mask width.
3. Metadata is stored in the most significant bits in CQE in this
mode because the registers copy code was not updated during the
metadata conversion to the big-endian format. Update this code to
avoid shifting the metadata in the datapath.

crypto/mlx5: add DEK object management

A DEK (Data encryption Key) is an mlx5 HW object which represents
the cipher algorithm key.
The DEKs are used during data encryption/decryption operations.

In symmetric algorithms like AES-XTS, we use the same DEK for both
encryption and decryption.

Use the mlx5 hash-list tool to manage the DEK objects in the PMD.

Provide the compare, create and destroy functions to manage DEKs in
hash-list and introduce an internal API to setup and unset the DEK
management and to prepare and destroy specific DEK object.

The DEK hash-list will be created in dev_configure routine and
destroyed in dev_close routine.

net/sfc: support flow action count in transfer rules

For now, a rule may have only one dedicated counter, shared counters
are not supported.

HW delivers (or "streams") counter readings using special packets.
The driver creates a dedicated Rx queue to receive such packets
and requests that HW start "streaming" the readings to it.

The counter queue is polled periodically, and the first available
service core is used for that. Hence, the user has to specify at least
one service core for counters to work. Such a core is shared by all
MAE-capable devices managed by sfc driver.
