Showing an arrow for an empty expander row for the event confuses the user.
The user may misunderstand there is the information behind the arrow and then
the user will click it but will not get any response from the panel.
Therefore, to prevent confusing the user, the expander will be hidden for a
event with an empty description.

The new UX implementation includes
1. Showing the security level using a number.
2. Showing descriptions of events and HSI checking items.
3. Change the style of the security level number.
4. Add the status icon and label for each HSI checking item.

The Firmware Security panel exposes the host security levels
and details. The information is generated by fwupd. The panel
also exposes hardware configuration changes to pinpoint the
configuration changing time.
Currently this panel shows:
- HSI and secure boot status
- Details of HSI and secure boot
- Configuration changelog
- Digested security level
- Extended protection
