Remove run-make-support CHANGELOG

Hopelessly outdated, and this support library is purely internal.

-# Changelog
-
-All notable changes to the `run_make_support` library should be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and the support
-library should adhere to [Semantic Versioning](https://semver.org/spec/v2.0.0.html) even if it's
-not intended for public consumption (it's moreso to help internally, to help test writers track
-changes to the support library).
-
-This support library will probably never reach 1.0. Please bump the minor version in `Cargo.toml` if
-you make any breaking changes or other significant changes, or bump the patch version for bug fixes.

-## [0.2.0] - 2024-06-11
-
-### Added
-
-- Added `fs_wrapper` module which provides panic-on-fail helpers for their respective `std::fs`
-  counterparts, the motivation is to:
-    - Reduce littering `.unwrap()` or `.expect()` everywhere for fs operations
-    - Help the test writer avoid forgetting to check fs results (even though enforced by
-      `-Dunused_must_use`)
-    - Provide better panic messages by default
-- Added `path()` helper which creates a `Path` relative to `cwd()` (but is less noisy).
-
-### Changed
-
-- Marked many functions with `#[must_use]`, and rmake.rs are now compiled with `-Dunused_must_use`.
-
-## [0.1.0] - 2024-06-09
-
-### Changed
-
-- Use *drop bombs* to enforce that commands are executed; a command invocation will panic if it is
-  constructed but never executed. Execution methods `Command::{run, run_fail}` will defuse the drop
-  bomb.
-- Added `Command` helpers that forward to `std::process::Command` counterparts.
-
-### Removed
-
-- The `env_var` method which was incorrectly named and is `env_clear` underneath and is a footgun
-  from `impl_common_helpers`. For example, removing `TMPDIR` on Unix and `TMP`/`TEMP` breaks
-  `std::env::temp_dir` and wrecks anything using that, such as rustc's codgen.
-- Removed `Deref`/`DerefMut` for `run_make_support::Command` -> `std::process::Command` because it
-  causes a method chain like `htmldocck().arg().run()` to fail, because `arg()` resolves to
-  `std::process::Command` which also returns a `&mut std::process::Command`, causing the `run()` to
-  be not found.
-
-## [0.0.0] - 2024-06-09
-
-Consider this version to contain all changes made to the support library before we started to track
-changes in this changelog.
-
-### Added
-
-- Custom command wrappers around `std::process::Command` (`run_make_support::Command`) and custom
-  wrapper around `std::process::Output` (`CompletedProcess`) to make it more convenient to work with
-  commands and their output, and help avoid forgetting to check for exit status.
-    - `Command`: `set_stdin`, `run`, `run_fail`.
-    - `CompletedProcess`: `std{err,out}_utf8`, `status`, `assert_std{err,out}_{equals, contains,
-      not_contains}`, `assert_exit_code`.
-- `impl_common_helpers` macro to avoid repeating adding common convenience methods, including:
-    - Environment manipulation methods: `env`, `env_remove`
-    - Command argument providers: `arg`, `args`
-    - Common invocation inspection (of the command invocation up until `inspect` is called):
-      `inspect`
-    - Execution methods: `run` (for commands expected to succeed execution, exit status `0`) and
-      `run_fail` (for commands expected to fail execution, exit status non-zero).
-- Command wrappers around: `rustc`, `clang`, `cc`, `rustc`, `rustdoc`, `llvm-readobj`.
-- Thin helpers to construct `python` and `htmldocck` commands.
-- `run` and `run_fail` (like `Command::{run, run_fail}`) for running binaries, which sets suitable
-  env vars (like `LD_LIB_PATH` or equivalent, `TARGET_RPATH_ENV`, `PATH` on Windows).
-- Pseudo command `diff` which has similar functionality as the cli util but not the same API.
-- Convenience panic-on-fail helpers `env_var`, `env_var_os`, `cwd` for their `std::env` conterparts.
-- Convenience panic-on-fail helpers for reading respective env vars: `target`, `source_root`.
-- Platform check helpers: `is_windows`, `is_msvc`, `cygpath_windows`, `uname`.
-- fs helpers: `copy_dir_all`.
-- `recursive_diff` helper.
-- Generic `assert_not_contains` helper.
-- Scoped run-with-teardown helper `run_in_tmpdir` which is designed to run commands in a temporary
-  directory that is cleared when closure returns.
-- Helpers for constructing the name of binaries and libraries: `rust_lib_name`, `static_lib_name`,
-  `bin_name`, `dynamic_lib_name`.
-- Re-export libraries: `gimli`, `object`, `regex`, `wasmparsmer`.
