This updates all Qt components to their latest versions.

Notice that the qtcanvas3d doens't seem to be shipped after 5.12, so this 
updated to the latest from that series.

I compiled all components and all finished successfully. Except for the 
qtwebengine one
which generates a compile/link error I did not manage to resolve.

This patch should thus be seen as a work-in-progress as it did most of the 
work and I hope someone can help me finish this.

Additionally, I'm sure some dependencies will need upgrading too.
For instance kitemviews 5-63 fails to compile and upstream has 5.69 already...

Thanks
