Add a new flag -minimal for NVRTC compilation. The -minimal flag omits certain language features to reduce compile time for small programs. In particular, the following are omitted:
Texture and surface functions and associated types (for example, cudaTextureObject_t).
CUDA Runtime Functions that are provided by the cudadevrt device code library, typically named with prefix “cuda”, for example, cudaMalloc.
Kernel launch from device code.
Types and macros associated with CUDA Runtime and Driver APIs, provided by cuda/tools/cudart/driver_types.h, typically named with the prefix “cuda” for example, cudaError_t.
This might be worth investigating in the future (post #1150)
This will require changes to our headers to prevent nvrtc from seeing cudaStream_t etc. Actually adding it to JitifyCache::compileKernel is trivial (though potentially it can be made a runtime decision rather than compile time for cuda 12.0-12.3 builds, depending on how nvrtc works)
