fix(windows): use osc_to_u16 even without read scancode (#1321)

This fixes an issue where keypad enter was not working correctly. I'm
not entirely sure why the conditional compile branch was written in the
first place; maybe I defaulted to it without thinking much about it. But
it seems correct to use osc_to_u16 regardless of llhook reading
mechanism given that output VK doesn't care about input reading mode.
