Use a new S3 bucket instead of mciuploads

This is being done for two reasons.

First, we want to move projects away from all using the shared `mciuploads` bucket.

Second, the credentials to access `mciuploads` are only available for the DB Tools Evergreen project for the `master` branch. When we make a PR off a different branch, we cannot see those credentials. That means those branches cannot interact with S3 in CI, which leads to lots of CI failures. Switching to a new bucket and using `ec2.assume_role` to access that bucket means this works on any branch.
