[9571] Create and use ObjectGuidGenerator/IdGenerator template classes.

Browse source 
* This is let finally hide guid structure in ObjectGuid.h/.cpp code.
* Shared related code.

NOTE: while switch to use new clasess one more problem has been detected
with not-safe code in .pdump work for future per-map multi-threading.
It's need rewrited before will possible safe use in like case.
For current single world thread case it's safe.
