msg: add function to reduce log level

Sometimes it's helpful to override this for specific mp_log instances,
because in some specific circumstances you just want to suppress log
file noise you never want to see.

-1 is an allowed value (for suppressing MSGL_FATAL==0). It looks like
the libplacebo wrapper still does this wrong, so it will probably
trigger UB in some cases. I guess I don't care, though.
