cmd/geth: make it possible to autopilot removedb (#28725)

Browse Source 
When managing geth, it is sometimes desirable to do a partial wipe; deleting state but retaining freezer data. A partial wipe can be somewhat tricky to accomplish. 

This change implements the ability to perform partial wipe by making it possible to run geth removedb non-interactive, using command line options instead.
