This is preparation for enabling an eslint indentation configuration. 90% of these changes are just fixes for indentation errors that have snuck into the codebase over the years; the others are more significant reformatting to make eslint happy (that are not otherwise actually improvements). The one area that we do not attempt to work on here is the "switch/case" indentation.
