Clear Metadata on all files processed via Macro

### Your idea

Option to add 'Clear Metadata' to a Macro chain. Every file processed by this Macro would have Metadata removed.

### Problem to be solved

Better results when bulk processing files in specific cases. Currently I can use "EditMetaData:" in my Macro and it will display the Metadata screen each process and I can click 'Clear' and 'Ok' but this is not efficient or bulk processing. We would like this to be automatic.

### Prior art

I have used this tool before to bulk remove metadata from mp3s https://crates.io/crates/id3-image

### Additional context

Thanks

Start by tracing the existing "EditMetaData:" Macro command and the Metadata screen's "Clear" action. Determine how a Macro processes each file and make the requested option remove metadata without opening the screen; done when every file in the Macro chain is processed this way.
