Move kotlin.test common annotations tests

Place them in tests of kotlin-test-annotations-common, so that every
platform module that implements that common module (e.g. kotlin-test-junit,
kotlin-test-junit5, kotlin-test-testng) gets these tests run.

Improve test for BeforeTest/AfterTest annotations to check that they are
invoked before/after _each_ test method.
