MT: Hide superfluous size information when running as package manager

As the uncompressed size is only checked for already installed and new
component selections (+ dependencies), it makes sense to show the size
information for only these components in the ComponentSelectionPage
"Size" column.

This makes it easier to follow how the component selection affects
installation size.
