Summary: Ref T7604. Remove the `reenter_if_this_is_arcanist_or_libphutil` function. Some discussion in D12945.

Test Plan: Ran `./bin/arc --trace help` and saw things happen as expected.

* NOTE: SPOOKY BLACK MAGIC

* libphutil other than the one we loaded, reenter the script and force it
* to use the current working directory instead of the default.
*
* In the case of execution inside arcanist/, we force execution of the local
* arc binary.
*
* In the case of execution inside libphutil/, we force the local copy to load
* instead of the one selected by default rules.
*
* @param PhutilConsole Console.
* @param ArcanistWorkingCopyIdentity The current working copy.
