devlink: Add API to register packet trap groups

Browse Source 
Currently, packet trap groups are implicitly registered by drivers upon
packet trap registration. When the traps are registered, each is
associated with a group and the group is created by devlink, if it does
not exist already.

This makes it difficult for drivers to pass additional attributes for
the groups.

Therefore, as a preparation for future patches that require passing
additional group attributes, add an API to explicitly register /
unregister these groups.

Next patches will convert existing drivers to use this API.
