This command takes a list of ports, and causes the final state of the installed directory to be as-if one ran the install on an empty installed directory (removing any unnecessary packages). This is especially useful with the new `--x-install-root` option, which allows one to set the `installed` directory for vcpkg to use. Additionally, as a drive-by, we do some `stdfs` clean-up and add a `.is_feature()` member function to BinaryParagraph (as opposed to checking for `.feature().empty()`, which is far less clear to read). This feature is experimental.
