libobs: Reduce unnecessary logging (info -> debug)

(Note: This commit also modifies coreaudio-encoder, win-capture, and
win-mf modules)

This reduces logging to the user's log file.  Most of the things
specified are not useful for examining log files, and make reading log
files more painful.

The things that are useful to log should be up to the front-end to
implement.  The core and core plugins should have minimal mandatory
logging.
