[GPU] Revised unique ID setting scheme. (#10548)

* Revised unique ID setting scheme. Previously it was using program id to distinguish the loop body networks' id.
However, it results in cl cache miss for same network loaded multiple time, because program ids are differnt.
Now revised it to use parent primitive id instead of program_id for unique id of nodes in body networks.

* Revised adding unique_id to entry points to have a temporal number as unique id

* Revert the canceld change

* Added test to check whether two networks loaded from same function creates same cl cache
