This patch annotates the `Demangle` interface with\na new `DEMANGLE_ABI` annotation, which behaves like the `LLVM_ABI`. This\nannotation currently has no meaningful impact on the LLVM build;\nhowever, it is a prerequisite to support an LLVM Windows DLL (shared\nlibrary) build.\n\n## Overview\n\n1. Add a new `Demangle/Visibility.h` header file that defines a new\n`DEMANGLE_ABI` macro. The macro resolves to the proper DLL export/import\nannotation on Windows and a \"default\" visibility annotation elsewhere.\n2. Add a new `LLVM_ENABLE_DEMANGLE_EXPORT_ANNOTATIONS ` `#cmakedefine`\nthat is used to gate the definition of `DEMANGLE_ABI`.\n3. Code-mod annotate the public `Demangle` interface using the\n[Interface Definition Scanner (IDS)](https://github.com/compnerd/ids)\ntool.\n4. Manually fix-up `#include` statements for consistency.\n5. Format the changes with `clang-format`.\n6. Add a \"stub\" version of `Visibility.h` under `libcxxabi/src/demangle`\nthat always defines `DEMANGLE_ABI` to nothing.\n7. Update the canonical `libcxxabi/src/demangle/ItaniumDemangle.h`\ninstead of the llvm copy, and run `cp-to-llvm.sh` to ensure the llvm\ncopy matches. NOTE: we rely on `ccp-to-llvm.sh` not copying\n`Visibillity.h` as is already the case for `DemangleConfig.h`.\n\n## Background\n\nThis PR follows the pattern established with the `llvm-c` changes made\nin #141701.\n\nThis effort is tracked in #109483. Additional context is provided in\n[this\ndiscourse](https://discourse.llvm.org/t/psa-annotating-llvm-public-interface/85307),\nand documentation for `LLVM_ABI` and related annotations is found in the\nLLVM repo\n[here](https://github.com/llvm/llvm-project/blob/main/llvm/docs/InterfaceExportAnnotations.rst).\n\n## Validation\n\nLocal builds and tests to validate cross-platform compatibility.
