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.
