Conformance report: Include all device aspects

The device information we [currently print](https://github.com/KhronosGroup/SYCL-CTS/blob/3197f433c6cc4a834f73a381df55270346798e05/util/device_manager.cpp#L77) inside conformance reports is rather limited (only whether FP16 and FP64 are supported). We should include all [`device aspects`](https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#sec:device-aspects), and possibly some additional [device information descriptor values](https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#_device_information_descriptors).

Start in util/device_manager.cpp at the linked conformance-report code, then compare its current device information with the SYCL 2020 device-aspects specification. Determine which device aspects, and any additional device information descriptors, should be reported. Done means conformance reports include the requested device information consistently.
