Improve build configuration of integration tests

* publication-validator is renamed to integration-testing;
* Each test is now in a separate source set, which allows for more
  flexibility in their configuration; for example, failing to set
  `dryRun=true` doesn't prevent tests other than NPM to run, and
  it is possible to run the tests (and their dependencies)
  separately.

+# Integration tests
+
+This is a supplementary subproject of kotlinx.coroutines that provides
+integration tests.
+
+The tests are the following:
+* `NpmPublicationValidator` tests that version of NPM artifact is correct and that it has neither source nor package dependencies on atomicfu
+ In order for the test to work, one needs to run gradle with `-PdryRun=true`.
+ `-PdryRun` affects `npmPublish` so that it only provides a packed publication
+ and does not in fact attempt to send the build for publication.
+* `MavenPublicationValidator` depends on the published artifacts and tests artifacts binary content and absence of atomicfu in the classpath
+
+All the available tests can be run with `integration-testing:test`.
