[llvm] annotate remaining Support and ADT library interfaces for DLL export (#145354)

## Purpose

This patch is one in a series of code-mods that annotate LLVM’s public
interface for export. This patch annotates the remaining LLVM Support
and ADT interfaces that were missed in, or modified since, previous
patches. 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

The bulk of these changes were generated automatically using the
[Interface Definition Scanner (IDS)](https://github.com/compnerd/ids)
tool, followed formatting with `git clang-format`.

The following manual adjustments were also applied after running IDS:
- Annotate the private method `IEEEFloat::addOrSubtractSignificand` with
`LLVM_ABI` because it is used by a unit test friend class.
- Annotate several `friend` function declarations with `LLVM_ABI_FRIEND`
since the corresponding function declarations are annotated with
`LLVM_ABI` (required by MSVC).

## 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
