RFR: 8354547: REDO: Force clients to explicitly pass mem_tag value, even if it is mtNone [v12]

[Gerard Ziemski]

> Redo for a follow-up to https://github.com/openjdk/jdk/pull/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.
> 
> Testing: passes tier1 locally on my mac, Mach5 tier1-5 in progress
