The implementations of `LogEvent.toImmutable()` either use serialization or one of the `Log4jLogEvent.Builder` constructors and custom per class code. This PR: - Redirects all implementation of `LogEvent.toImmutable` to the `Builder(LogEvent)` constructor (except `Log4jLogEvent.toImmutable()`) - Improve the constructor to create really immutable and thread-safe instances. - Removes the usage of `ThrowableProxy` for purposes not related to serialization. - Fixes some implementations of `ReusableMessage.memento()`. - Uses `ReusableMessage.memento()` instead of `ImmutableMessage` where applicable.
