Switch Windows CI build to sbt (w/ some sbt build improvements)

- Use sbt in `integrate/windows`: This essentially combines the Unix CI
  jobs `validate/publish-core` and `validate/test`, first publishing a
  local release built with STARR and then building a new version with
  that and running all tests on it.

- Unify repository handling across build scripts: A new function
  `generateRepositoriesConfig` in `common`, based on the existing code
  in `integrate/bootstrap`, writes the `repositories` file for sbt,
  either with or without an extra bootstrap repository for resolving a
  previously built version. It is used in all CI scripts to ensure that
  artifacts are only resolved through the sanctioned proxies and
  upstream repositories.

- The repository URL arguments in `setupPublishCore` and
  `setupValidateTest` are now optional as well. These commands are used
  without a URL from `integrate/windows`, which publishes to `local`
  instead of a temporary remote repository.

- `testAll` is now a task instead of a command. It runs the same
  sequence of sub-tasks as before but does not propagate failures
  immediately. It always runs all subtasks and reports errors at the
  end.

- The `generateBuildCharacterPropertiesFile` task now includes all
  properties from `versions.properties` (whose values have potentially
  been overwritten with `-D` options) in `buildcharacter.properties`.
