image_tool: Refactor logic for replacing components.

1. Add CopyComponentsInImage() and ReplaceComponentsInImage() to copy
   and replace components in a shim image.
2. Move GetDiskUsage() and GetRemainingSize() to SysUtils.
3. Move ExpandPartition() and ShrinkPartition() to global functions.
4. If RMA metadata is not found, raise exception instead of returning
   None.
