Mostly remove "STDERR" and "STDOUT" constants from Arcanist


Mostly remove "STDERR" and "STDOUT" constants from Arcanist

Ref T13675. Ref T13556. The "STDOUT" and "STDERR" constants are defined by the PHP CLI SAPI, in cli_register_file_handles().

The "native arc" embedded PHP wrapper doesn't define these, and there's no real reason to define them, since they're just defined in terms of the PHP stream wrappers ("php://stdin", etc) anyway.

This patch isn't exhaustive (and a subsequent change should add lint, rejecting these magic constants) but is just trying to make native arc functional.

Test Plan: Created this revision with a standalone native arc binary.
