Summary Add a way to log which part of a serialized object failed IPC decoding

Sometimes, we receive crash reports caused by WebContent receiving an invalid IPC message. While we log which IPC message was invalid, we do not know which part of the message caused the decoding failure. This patch introduces a way to log the specific part of a serialized object that failed IPC decoding. This is particularly important for IPC messages that send large objects, such as `WebPageCreationParameters` or `WebProcessCreationParameters`, which contain numerous objects with validators that could potentially cause a crash.
