[CMake] clang-offload-bundler depends on intrinsics_gen

ClangOffloadBundler.cpp has the following include chain:

llvm/Bitcode/BitcodeWriter.h
llvm/IR/ModuleSummaryIndex.h
llvm/IR/Module.h
llvm/IR/Function.h
llvm/IR/Argument.h
llvm/IR/Attributes.h
llvm/IR/Attributes.gen

This means clang-offload-bundler needs to depend on intrinsics_gen.
