[VMA] Phase 3:- Hand all allocation & binding to VMA (#362)

This patch completely removes the Custom Sub allocator with VMA and delegates everything to the VMA.
Overall, the patch integrates VMA and simplifies memory management.
Once these changes pass the testing, it will be used as a base for further improvement.
Note to testers, test for stability and performance.
