Nerfed the hell out of memory update overhead

[kevingranade]

Summary

SUMMARY: None

Purpose of change

Fixes #37072
Bionic memory bank power usage is super high, at very high skill levels it looks like this can kick in about once a minute or so, and at 25kJ an activation, that drains bionic power absurdly quickly.

Describe the solution

Massively dropped power consumption of memory bank CBM, from 25kJ an activation to 25J an activation. That's roughly 60W of continuous power consumption, which is still pretty high, but we're basically saying it's analagous to a DRAM memory refresh over a stupendous number of memory cells.

Describe alternatives you've considered

IDK, I don't think there's a super reasonable way to balance this CBM as written, so all I'm trying to do here is pound out an utterly insane outcome.

Testing

None, I'm not worried about this having side effects.
