Michelson: Fix gas consumption in traced execution

Context

Fixes: #3971 (closed). See the description of the issue for more context.

Depends on !6546 (merged) and !6565 (merged) which enriches some regression traces to give a better picture of the issue.

TODO:

• while we are at it, I think that we should remove most of the code in log and klog because it is redundant.
• add an entry in the changelog

Manually testing the MR

A property that should hopefully hold now is that the "remaining gas" quantity reported in the regression traces is strictly decreasing. I haven't checked this property though.
