Change default uvision exporter to uvision5

uVision4 is no longer maintained by the Keil team (support was stopped
long time ago).

This is why we need to make the uvision exporter able to generate uVision5
projects by default (which is based on software packs).

Also, adding note that the uvision4 exporter is now deprecated and will be
removed in the future.
