Microdroid Demo App supports non-protected and protected vm

[Description]
The Microdroid demonstration application has been enhanced to support
both non-protected and protected virtual machines (VMs). The default
behavior is to launch a non-protected VM instance.

Users now have the option to start a protected VM by selecting a newly
implemented checkbox within the application's user interface.

Since some chipsets are limited to supporting only non-protected VMs.
This compatibility consideration is essential for the application's
deployment across diverse hardware configurations.
