chore: sdk.Int to math.Int (#12132)
## Description

When locally working with golangci-lint, we can see that there were many deprecation warnings about sdk.Int.  This PR resolves that and makes 1-2 other linting related changes.  Issue on linting coming next.

This also moves BitCurve to bitCurve.

I expect that this set of changes will require several pull requests, one of them to the settings for the linter. 

It also does a gofumpt, because we had various formatting-related linters fail, too.
