🔀 #442 - CUDA call tracer

Description

This PR adds a CUDA call tracer. The main purpose of the tracer is to hopefully help debug the illegal memory access crashes reported in #398 and #425. If there is a crash, the last 32 invocations of CUDA_CHECK will be printed to stderr before aborting. In my testing the overhead added by the tracer has negligible impact on performance.
