Rollup merge of #70777 - faern:use-assoc-int-consts2, r=dtolnay

Don't import integer and float modules, use assoc consts

Stop importing the standard library integer and float modules to reach the `MIN`, `MAX` and other constants. They are available directly on the primitive types now.

This PR is a follow up of #69860 which made sure we use the new constants in documentation.

This type of change touches a lot of files, and previously all my assoc int consts PRs had collisions and were accepted only after a long delay. So I'd prefer to do it in smaller steps now. Just removing these imports seem like a good next step.
