Update(DeviceProxy): Dynamically Determine Memory Allocation Size & Remove Compile-Time size Calculations (#48)

* Update(DeviceProxy): Dynamically Determine Memory Allocation Size & Remove Compile-Time size Calculations

- Modified the Device proxy class to determine memory allocation size at runtime.
- Updated all classes that include the Device proxy to use dynamic memory allocation.
- Removed compile-time memory size calculations.
- Ensured the allocated number of backend queue data structures matches the number of RO device contexts.
