Description
Would it feasible to support the cl_ext_buffer_device_address extension in clOn12?
More on that here: https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_API.html#cl_ext_buffer_device_address
I think the core of this spec can be supported through GetGPUVirtualAddress method
This would help us support OpenCLOn12 as an OpenCL backend for Windows for our own software, which relies on either this or SVM.
Its supported in Mesa's Rusticl and pocl drivers as of yet.

Research direction
Start by reading the linked OpenCL cl_ext_buffer_device_address specification and the Direct3D 12 GetGPUVirtualAddress API referenced in the issue. Determine the extension behavior that clOn12 would need to expose and whether that mapping is feasible; done means the support scope and validation approach are clear.
