* Updates the runtime options with a CustomAllocatorMap which allows to define a CustomAllocator for specific backends
* Change IBackendInternal interface to use a shared pointer to a custom allocator
* Update ClBackend.hpp/cpp to use the CustomAllocator
* Adds an example application and unit test which uses a CustomAllocator for GpuAcc
* Refactor of the interface to use MemorySource instead of the user Mapping cl_mem directly
* Modify the BackendRegistry to also hold a registry of CustomAllocators
* BackendRegistry Deregister will also deregister any allocators associated with that backend id
* set_global_allocator within the BaseMemoryManager so that it always matches the currently used allocator
