[ET-VK] Removing descriptor pool intialization from DescriptorPool ctor.

[trviv]

Stack from ghstack (oldest at bottom):

• [ET-VK] Return fence after waiting is done. #10787
• [ET-VK] Moving device capabilities check to DispatchNode and PrepackNode ctor. #10785
• [ET-VK] Reducing memory wastage by tightening DescriptorPoolConfig values. #10784
• -> [ET-VK] Removing descriptor pool intialization from DescriptorPool ctor. #10777

Descriptor pool is initialized with proper capacity while ComputeGraph is build, in ComputeGraph::prepare function.
Thus, initializing descriptor pool in constructor just add throwaway work.
