cl_ext_buffer_device_address requires us to set a fixed address for a given memory allocation. As this extension is intended to be implemented on top of vulkan we have to take its limitations into account. For SVM we'll add proper VM management interfaces, but zink won't be able to implement those, so here we are. The old interfaces added back in clover's time were modeled after a very bindful resource model and the frontend was require to bind all the used resources ahead of launch_grid. cl_ext_buffer_device_address and also SVM however will require us to dynamically attach a list of buffers used in a dispatch with known addresses, hence set_global_binding isn't really suited for those use cases. So PIPE_RESOURCE_FLAG_FIXED_ADDRESS is added to tell a driver that the address of a resource needs to stay the same over its lifetime, which then can be queried via pipe_screen::resource_get_address. All such buffers then can be either bound via set_global_binding or passed in via pipe_grid_info::globals.
