mlxsw: spectrum: Track used packet trap policer IDs
During initialization the driver configures various packet trap groups and binds policers to them. Currently, most of these groups are not exposed to user space and therefore their policers should not be exposed as well. Otherwise, user space will be able to alter policer parameters without knowing which packet traps are policed by the policer. Use a bitmap to track the used policer IDs so that these policers will not be registered with devlink in a subsequent patch.
