fix(win/input): fix false warnings about missing ViGEmBus

[cgutman]

Description

Invoking platf::supported_gamepads() during static initalization of config_t was leading to misleading warnings in the logs indicating lack of ViGEmBus. We should handle the !input case specially like we do for the inputino implementation.
