AMD GPU systems need not have a functional clGetDeviceInfo(..., CL_DEVICE_TOPOLOGY_AMD, ...). E.g., Fedora OpenCL with AMD GPU drivers, it seems. As the code stands it doesn't create a uniqueId, and leaves it null. If there are multiple GPUs, the device info is stored to null uniqueId and overwritten - and only one of these GPUs will be enumerated and visible to the miner. Fix this by providing a fall-back, constructing the uniqueId from the platform and device indexes. As is already the case for Intel GPU and CPU devices. Additionally, cosmetically, add a clearer, more self-describing struct for the AMD topology data.
The hard coded 1.66.0 Boost in Hunter no longer downloads, breaking the build. Change to the default hunter version.

To get Hunter to work I had to update the Boost version.
The previously specified version is no longer available for hunter to download.
