Pull request description:

  Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)

  The first 2 commits are fixups addressing review for the last bundle: #21391

  NEW note:
  1. I have opened #21766 which keeps track of potential improvements where the flaws already existed before the de-globalization work, please post on that issue about these improvements, thanks!

  Note to reviewers:
  1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
  2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
  3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
  1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
  2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
  3. Remove `old_function`

README.md

Test library

This contains files for the test library, which is used by the test binaries (unit tests, benchmarks, fuzzers, gui tests).

Generally, the files in this folder should be well-separated modules. New code should be added to existing modules or (when in doubt) a new module should be created.

The utilities in here are compiled into a library, which does not hold any state. However, the main file setup_common defines the common test setup for all test binaries. The test binaries will handle the global state when they instantiate the BasicTestingSetup (or one of its derived classes).
