[PATCH v3 1/9] eventdev: add capability flags for supported sched types

[Bruce Richardson <bruce.richardson@intel.com>]

Not all eventdev's support all scheduling types, for example, some may
only support atomic scheduling or others only support ordered
scheduling. There is currently no clear indication for each driver what
sched types it supports, so add capability flags to be indicated on
return from rte_event_dev_info_get() API.

Similarly add the possible scheduling types to the capabilities table in
the docs.
