WIP: Bzlmod part the thirty-fifth

As it turns out, we're using a very old version of Scalafmt that breaks
completely:

```txt
ERROR: rules_scala/test/scalafmt/BUILD:43:20:
  ScalaFmt test/scalafmt/test/scalafmt/formatted/formatted-test.scala.fmt.output failed:
  (Exit 1): scalafmt failed: error executing ScalaFmt command
  (from target //test/scalafmt:formatted-test)
bazel-out/darwin_arm64-opt-exec-ST-d57f47055a04/bin/scala/scalafmt/scalafmt
  '--jvm_flag=-Dfile.encoding=UTF-8' ... (remaining 1 argument skipped)

java.util.NoSuchElementException: last of empty IndexedSeq
```

This matches:

- scala/community-build#1680

Which mentions apparent fixes in:

- scalameta/scalameta#3235
- scalameta/scalafmt#3581

So the fix is to update Scalafmt, but given how we don't use
rules_jvm_external, that means a lot of manual updates to
third_party/repositories/scala_*.bzl. There doesn't appear to be a way
to automate this; there's no indication that the most recent update was
automated in any way:

- bazel-contrib#1543

So I'll plow through all the JARs and make the necessary changes:

- https://mvnrepository.com/artifact/org.scalameta/scalafmt-core

I can't update scala_2_11, since there's not a more recent compatible
version. But the changes to scala_2_12 and scala_2_13 should be similar,
and the changes to 2_13 should apply to 3_{1,2,3,4} as well.

I had to hack .scalafmt.conf and ScalafmtWorker.scala a bit. This may
make it incompatible with 2.11.
