#1503 Skip unneeded solid blocks

[Shell]

When I choose to skip existing files during extraction, 7zG 21.00 still performs dummy extraction of those files even when the whole solid block is skipped. I believe that 7-Zip checks whether to skip a file as soon as the archive operation comes to it. I suggest to change this behaviour and enumerate all files in the filesystem before archive operation. This way, 7-Zip will be able to filter out unused solid blocks and to not waste time on them.
