Modify header actions are allocated by mlx5_malloc which has a big
overhead of memory and allocation time.
One of the action types under the modify header object is SET_TAG,
The SET_TAG action is commonly not reused by the flows and each flow has
its own value.
Hence, the mlx5_malloc becomes a bottleneck in flow insertion rate in
the common cases of SET_TAG.
Use ipool allocator for SET_TAG action.
Ipool allocator has less overhead of memory and insertion rate and has
better synchronization mechanism in multithread cases.

common/mlx5: allocate cache list memory individually
Currently, the list's local cache instance memory is allocated with
the list. As the local cache instance array size is RTE_MAX_LCORE,
most of the cases the system will only have very limited cores.
allocate the instance memory individually per core will be more
economic to the memory.
This commit changes the instance array to pointer array, allocate
the local cache memory only when the core is to be used.

common/mlx5: add per-lcore cache to hash list utility
Using the mlx5 list utility object in the hlist buckets.
This patch moves the list utility object to the common utility, creates
all the clone operations for all the hlist instances in the driver.
Also adjust all the utility callbacks to be generic for both list and
hlist.

common/mlx5: add per-lcore sharing flag in object list
Without lcores_share flag, mlx5 PMD was sharing the rdma-core objects
between all lcores.
Having lcores_share flag disabled, means each lcore will have its own
objects, which will eventually lead to increased insertion/deletion
rates.

net/mlx5: manage list cache entries release
When a cache entry is allocated by lcore A and is released by lcore B,
the driver should synchronize the cache list access of lcore A.
The design decision is to manage a counter per lcore cache that will be
increased atomically when the non-original lcore decreases the reference
counter of cache entry to 0.
In list register operation, before the running lcore starts a lookup in
its cache, it will check the counter in order to free invalid entries in
its cache.

net/mlx5: minimize list critical sections
The mlx5 internal list utility is thread safe.
In order to synchronize list access between the threads, a RW lock is
taken for the critical sections.
The create\remove\clone\clone_free operations are in the critical
sections.
These operations are heavy and make the critical sections heavy because
they are used for memory and other resources allocations\deallocations.
Moved out the operations from the critical sections and use generation
counter in order to detect parallel allocations.

net/mlx5: add per-lcore cache to the list utility
When mlx5 list object is accessed by multiple cores, the list lock
counter is all the time written by all the cores what increases cache
misses in the memory caches.
In addition, when one thread accesses the list for add\remove\lookup
operation, all the other threads coming to do an operation in the list
are stuck in the lock.
Add per lcore cache to allow thread manipulations to be lockless when
the list objects are mostly reused.
Synchronization with atomic operations should be done in order to
allow threads to unregister an entry from other thread cache.
