Cycles defines some basic integer types since it cannot use the standard headers when compiling with NVRTC. NanoVDB however only does this when the "__CUDACC_RTC__" define is set and otherwise includes the standard "stdint.h" header which clashes with those typedefs. So for compatibility do the same thing in the Cycles kernel headers. See also T81454.
