Tweak formatting rules for attributes (#492)

The abundance of `@_spi(TokamakCore)` makes it harder to parse some of our code visually when skimming. I propose consistently moving attributes on declarations to separate lines. Here's an update to `.swiftformat` config with the new settings applied to the codebase.

* Tweak formatting rules

* Improve readability with newlines

* More newlines to visually separate declarations

* Fix build error caused by merge conflict
