eventdev: introduce link profiles

A collection of event queues linked to an event port can be
associated with a unique identifier called as a link profile, multiple
such profiles can be created based on the event device capability
using the function `rte_event_port_profile_links_set` which takes
arguments similar to `rte_event_port_link` in addition to the profile
identifier.

The maximum link profiles that are supported by an event device
is advertised through the structure member
`rte_event_dev_info::max_profiles_per_port`.
By default, event ports are configured to use the link profile 0
on initialization.

Once multiple link profiles are set up and the event device is started,
the application can use the function `rte_event_port_profile_switch`
to change the currently active profile on an event port. This effects
the next `rte_event_dequeue_burst` call, where the event queues
associated with the newly active link profile will participate in
scheduling.

An unlink function `rte_event_port_profile_unlink` is provided
to modify the links associated to a profile, and
`rte_event_port_profile_links_get` can be used to retrieve the
links associated with a profile.

Using Link profiles can reduce the overhead of linking/unlinking and
waiting for unlinks in progress in fast-path and gives applications
the ability to switch between preset profiles on the fly.

eventdev: add weight and affinity to queue attributes

Extended eventdev queue QoS attributes to support weight and affinity.
If queues are of the same priority, events from the queue with highest
weight will be scheduled first. Affinity indicates the number of times,
the subsequent schedule calls from an event port will use the same event
queue. Schedule call selects another queue if current queue goes empty
or schedule count reaches affinity count.

To avoid ABI break, weight and affinity attributes are not yet added to
queue config structure and rely on PMD for managing it. New eventdev op
queue_attr_get can be used to get it from the PMD.
