LOG: [llvm] annotate `LLVMCloneModule` for export (#145570)

## Purpose
This patch is one in a series of code-mods that annotate LLVM’s public
interface for export. This patch annotates the implementation of
`LLVMCloneModule ` with `LLVM_ABI` to match its declaration in
`llvm-c/Core.h`. The annotation currently has no meaningful impact on
the LLVM build; however, it is a prerequisite to support an LLVM Windows
DLL (shared library) build.

## Background
This effort is tracked in #109483. Additional context is provided in
[this
discourse](https://discourse.llvm.org/t/psa-annotating-llvm-public-interface/85307),
and documentation for `LLVM_ABI` and related annotations is found in the
LLVM repo
[here](https://github.com/llvm/llvm-project/blob/main/llvm/docs/InterfaceExportAnnotations.rst).

## Validation
Local builds and tests to validate cross-platform compatibility. This
included llvm, clang, and lldb on the following configurations:

- Windows with MSVC
- Windows with Clang
- Linux with GCC
- Linux with Clang
- Darwin with Clang
