  Log Message:
  -----------
  [CIR] Introduce the cir.sdk_version module attribute (#225953)

CIRGen records the platform SDK version on the module as a
`cir.sdk_version` string attribute, and LoweringPrepare's CUDA/HIP
registration reads it instead of  `getTargetInfo().getSDKVersion()` to gate
`__cudaRegisterFatBinaryEnd`, dropping one more `ASTContext` dependency
from the post-CIRGen pipeline.

LLVM IR already records the same fact as the "SDK Version" module flag
(`Module::setSDKVersion/getSDKVersion`), so an attribute on the module
is proper.
