21b3b37d - [NVPTX] Validate user-specified PTX version against SM version (#174834)

[NVPTX] Validate user-specified PTX version against SM version (#174834) When users explicitly specify a PTX version via `-mattr=+ptxNN` that's insufficient for their target SM, we now emit a fatal error. Previously, we silently upgraded the PTX version to the minimum required for the target SM. When no SM or PTX version is specified, we now use PTX 3.2 (the minimum for the default SM 3.0) instead of PTX 6.0.
