RFR: 8344883: Do not use mtNone if we know the tag type [v5]

[Gerard Ziemski]

> This is a follow-up to #21843. Here we are focusing on removing the mem tag paremeter with default value of mtNone, to force everyone to provide mem tag, if known.
> 
> I tried to fill in tag, when I was pretty certain that I had the right type.
> 
> At least one more follow-up will be needed after this, to change the remaining mtNone to valid values.
