Check TCC/WDDM modes during Device initialization #208

To work around mempools being unavailable, we need

1. Check CU_DEVICE_ATTRIBUTE_TCC_DRIVER and branch out a separate treatment
   • For our purpose, it might also be sufficient to just check CU_DEVICE_ATTRIBUTE_MEMORY_POOLS_SUPPORTED
2. Implement a default allocator for TCC
   • Implement a concrete MemoryResource instance that just wraps cudaMalloc/cudaFree
   • Document this divergence from other platforms as a known issue
