Summary: Ref T13098. The name of this option is needlessly obscure/verbose, and we now require it come first so it should be unambiguous even if we add `arc borrow-a-book` later.
Test Plan: Grepped for `--load-phutil-library`.

Summary:
Ref T13098. This makes "arc help" kind-of sort-of work again.
Previously, "arc help" was completely custom and hard-coded. Now it just proxies the generic libphutil "help" workflow. The two flows are substantially similar, although old `arc help` was a little more brief than the new version is. The old `arc help --full` was more similar to the default:
| Command | Old Behavior | New Behavior |
|---|---|---|
| `arc` | Tells you to run `arc help`. | Plan: make this a bit richer and give a quick summary of workflows. |
| `arc help` | Gives you a summary of workflows. | Gives you a detailed list of workflows. |
| `arc help --full` | Gives you a detailed list of workflows. | No such flag. |
| `arc --help` | Same as `arc help`. | Same as `arc`. Plan: same as `arc help`. |
| `arc help <workflow>` | Full workflow help. | Full workflow help. |
| `arc <workflow> --help` | As above. | As above. |
Overall this is largely the same and lets us delete a bunch of code.
Test Plan:
Ran `arc`, `arc help`, `arc --help`, `arc --help diff`, `arc diff --help`, `arc help diff`, `arc help help`.
These commands largely do something sensible now, with caveats per above.

Summary:
Ref T13098. Depends on D19675. This change is headed to the `untamed-wilds` branch.
This change prevents `arc` from running `arc diff`, so I'm copy/pasting it.
This change also completely breaks `arc`, but I'm just generally trying to do this rewrite step-by-step so we have at least a bit of context to refer to in the future.
The major change here is to turn both `arc` and `phage` into scripts which start an `ArcanistRuntime`. This runtime then decides which workflows (like "diff", "patch", or "remote") are available based on `$argv[0]`. This turns `arc` into more of a CLI tools platform: we can build `phage` on it, third parties can build `my-companion-tool-thing`, etc. But all the different entry points can share a lot of infrastructure like: `help`, `alias`, shell-complete, configuration, Conduit, prompting, `--trace`, extension infrastructure, and so on.
`ArcanistRuntime` is roughly a slightly more modern version of `scripts/arcanist.php`. That will be removed eventually, but not everything has ported yet.
Test Plan: This code basically doesn't run yet, although the next patch runs at least a little bit.
