Jens Johansen 4d3d70af23 [kernel] Format kernel
Kernel sdk version was bumped from 3.6 to 3.12 in
https://dart-review.googlesource.com/c/sdk/+/487542 (and to `^3.12.0-0`
in https://dart-review.googlesource.com/c/sdk/+/487880) but the source
was never formatted.

This is, if nothing else, bad for reviews, where editing a file changes
the file in lots of places because of new formatting.

This CL is the result of running

```
out/ReleaseX64/dart-sdk/bin/dart format pkg/kernel/
```

but also updates the formatter version used by a source generator
(`pkg/front_end/tool/visitor_generator.dart`) so things agree.
