[Bazel] Add include/llvm/Transforms/Utils/ModuleUtils.h to work around layer violation after D116542

There is a layer violation and can break clang -fmodule-name=X -fmodules-strict-decluse builds:

* LLVMTransformUtils has `#include "llvm/Bitcode/BitcodeWriterPass.h"`
* LLVMBitWriter depends on LLVMTransformUtils after D116542

Temporarily work around the issue.
