Maximum number of scheduling groups is restricting and unintuitively retrieved

Maximum number of scheduling groups is very short:

• for basic scheduler 28 (NUM_SCHED_GRPS - SCHED_GROUP_NAMED)
• for SP scheduler is 9
• for iquery scheduler is 253 (ok)
• etc.

Ideally, unless HW limitations, ODP should be able to create one scheduler group per core.

Also, retrieving the number of scheduler groups with queue capabilities API (odp_queue_capability()) is un-intuitive, considering the fact that ODP has a certain number of scheduler related APIs (odp_schedule_group_create(), odp_schedule_group_destroy(), odp_schedule_group_join(), odp_schedule_group_info(), etc.)
