js: Fix a bunch of indentation issues found by eslint.

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.
