Platform types (QoS): refactor QoS Priority Level type per 3GPP TS 23.501

Browse Source 
QoS Priority Level range is 1-127, fits in uint8_t (3GPP TS 23.501 §5.7.3.3).

Refactor qos_priority field in pdusession_level_qos_parameter_t to use
qos_priority_level_t typedef (uint8_t) instead of uint64_t. Also,
improve documentation.

Changes:
- Add qos_priority_level_t typedef (uint8_t), more efficient than uint64_t
- Change pdusession_level_qos_parameter_t.qos_priority from uint64_t
  to qos_priority_level_t
- Add MIN_QOS_PRIORITY_LEVEL (1) and MAX_QOS_PRIORITY_LEVEL (127)
  defines for range checks
