Looking through context members alone when searching for a specific device isn't enough anymore since now descendent devices of context members can be used within that context as well. Change the logic to look for the device in the cache instead.

Subdevices, subsubdevices, etc. It's a term used in the spec: https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#descendent-device
