Added way to retrieve coroutine information without an agent
in target JVM. 'kotlin.debugger.coroutines.switch' provides
two possibilities to test coroutines.
Agent way gets activated once kotlinx.coroutines.debug.DebugProbes
started with javaagent.
Library-less ways use DispatchedContinuation or ChildContinuationImpl
classes to retrieve coroutine information and stack traces.
Smartcasts between partial and full resolution mode should almost never match,
comparing smartcasted types in test runner is incorrect in general case.
Mute failing test until decision about correct behaviour (KT-35922).
