cpu-sched: Optimize search for cpu affinity fixed app

This patch includes
  - Change serach for fixed cpu affnity apps
	(using the hashtable of apps by calling
	'fixed_app_and_service_exist_check(name, APP_TYPE) func')

resourced manages all per-app configurations
('Private' section) using a hashtable.
On the other hand, resourced (cpu-sched) managed cpu affinity fixed apps
using a list instead of hashtable.
That is, when resourced (cpu-sched) detects app launch or app status change,
it searches the list linearly to know whether the app requires fixed cpu affinity or not.
(Linear search is normally slow when app list size is big)

resourced (cpu-shced) will
  - use the hastable of the per-app configuration when searching an app
  - use the legacy list to apply something to all fixed cpu affinity apps
