Refactor fc_pool API to create generic fs_pool API, as HW steering has
more flow steering elements which can take advantage of the same pool of
bulks API. Change fs_counters code to use the fs_pool API.

Unfortunately it seems that clang-19 doesn't know how to handle
__counted_by() when used like this:
drivers/net/ethernet/mellanox/mlx5/core/fs_counters.c:442:36: error: 'counted_by' argument must be a simple declaration reference
442 | struct mlx5_fc fcs[] __counted_by(fs_bulk.bulk_len);
Thanks Simon, from code perspective, bulk_len should be now in the inner
struct fs_bulk.
Keen Cook, is that going to be supported in the future? for now I will
just remove __counted_by() from this struct.
