[llvm] annotate new symbols for DLL export (#148658)
## Purpose
This patch is one in a series of code-mods that annotate LLVM’s public
interface for export. This patch annotates symbols that were added to
LLVM in the last two weeks and were missed by previous code-mods. The
annotations currently have no meaningful impact on the LLVM build;
however, they are 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).
## Overview
These changes were generated automatically using the [Interface
Definition Scanner (IDS)](https://github.com/compnerd/ids) tool,
followed formatting with `git clang-format`.
## 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
