libcamera: Add a DebugMetadata helper

Debug metadata often occurs in places where the metadata control list is not available e.g. in queueRequest() or processStatsBuffer() or even in a class far away from the metadata handling code. It is therefore difficult to add debug metadata without adding lots of boilerplate code. This can be mitigated by recording the metadata and forwarding it to the metadata control list when it becomes available. To solve the issue of code that is far away from the metadata context, add a chaining mechanism to allow loose coupling at runtime.
