options: handle terminal/logging settings eagerly

Update msg.c state immediately if a terminal or logging setting is set.
Until now, this was delayed until mp[v]_initialize() was called. When
using the client API, you could easily miss logged error messages, even
when logging was initialized early on by calling
mpv_request_log_messages().

(Properties can't be used for this either, because properties do not
work before mpv_initialize().)
