Add nsListApplicationTitle2

Added another nsListApplicationTitle function because it requires smaller buffer (space for only one nsApplicationControlData unlike nsListApplicationTitle2) which will be more useful in memory constrained use. Also it's officially used by qlaunch.

Now I went back to previous approved data but with comment changed, because it turns out that expected tmem size was smaller. I was assuming it is the same as for original ListApplicationTitle because for Cmd421 on switchbrew it states that:
This is essentially the same as [ListApplicationTitle](https://switchbrew.org/wiki/NS_services#ListApplicationTitle) except the ApplicationControlSource is used here (ListApplicationTitle ignores it and uses 0xF0 instead).
Which needs bigger buffer.

But now I checked code and it's

  if ( 0x308 * v5 + 0x1D000 > a5 )
    return 0x5010LL;
