Treewide codestyle cleanup (#765)

- Updated gitignore and checked in the IDE's codestyle config
- Removed spotless as the underlying ktlint backend has failed to resolve the super frustrating import order bug[1] in nearly a year
- Reformat the entire codebase based on the previously committed code style configuration.
