Complete logging with SLF4J in Typed, #26537

* TestAppender interaction with LoggingEventFilter
  * TestAppender plays the same role as classic TestEventList
* replace Sl4jLoggingEvent.java
  * include MDC in testkit.LoggingEvent to allow for custom filter
    testing MDC
* fix tests
* fix log events in BehaviorSetKit, using SubstituteLogger
* MDC in EventSourcedBehavior
  * using raw MDC to set the persistenceId and persistencePhase fields
  * avoid access to MDC ThreadLocal if log isn't used

* Automatically enable eventStream Slf4jLogger for Typed (PR #27583)
  * amend the ActorSystem config on startup when config akka.use-slf4j=on
    and akka-slf4j in classpath
  * akka.use-slf4j is defined in akka-actor-typed reference.conf
  * also enable the Slf4jLoggingFilter automatically
  * remove config in tests

* Include actor path as akkaSource in MDC (PR #27587)
  * move logger init to ActorContextImpl since not specific to untyped (ActorContextAdapter)
  * careful to not access MDC ThreadLocal if logging isn't used (per message)
  * MDC is cleared (if used) from aroundReceive in ActorAdapter after processing each message
  * also changed MDC for EventSourcedBehavior to rely on context.log and the outer MDC.clear()
  * just removing the MDC values is not enough because the empty Map remains in the ThreadLocal

* Optimization of MDC interceptor (PR #27610)

* Extension methods to Logger as workaround for overload and varargs problem (PR #27605)
  * "ambiguous reference to overloaded definition" for 2 arg method
  * varargs not supported for primitive types
  * providing extension methods info2 and infoN (and friends) via implicit class LoggerOps
    as more convenient workaround for these problems

* New API for Typed LoggingEventFilter (PR #27611)
  * builder style
  * will make it easier to add more conditions
  * all conditions are AND:ed together which makes it easier to define custom filters
  * simplifies the implementation as a bonus
  * javadsl
  * use new api in all tests
  * leeway setting
  * verify that occurrences = 0 works
  * use javadsl in two tests
  * change interceptLogger, and some other feedback

* Testing utility to silence logging until failure (PR #27588)
  * Logback appender that captures all log events and can flush them
    later to other appenders
  * LogCapturing mixin for ScalaTest that flush the captured logging events
    when a test fails. Also clears the captured events after all tests.
  * Configuration in logback-test.xml
  * log capturing for JUnit tests too, using TestRule
  * Silence initial setup logging from Logback
  * make LogCapturing public
  * use LogCapturing in all tests
    * aside from multi-jvm, and a few extending AkkaSpec, so far
  * a few doc tests needed debug level

* mention in migration guide
* rename setLoggerClass to setLoggerName
* check for logback dependency to give nicer error message
* fix filterKeys, deprecated in 2.13
