power-utils: Add --compare option
This option is to get a latest version from a list of PSU versions.
Due to the --compare option requires a list of strings and only one
option is supported at the same time, it's easier to switch to CLI11 to
parse the arguments.
Also add --raw option that outputs the text without linefeed.
Tested: Verify both --get-version and --compare works on Witherspoon.
