[Development] Branching from '5.12' to '5.12.11' done

[Jani Heikkinen]

Hi all,

We have branched '5.12.11' from ' 5.12' today. So from now on '5.12' is for Qt 5.12.12 and all changes targeted to Qt 5.12.11 release must be cherry-picked in '5.12.11' as well.

The target is to release Qt 5.12.11 Thu 18th May.

br,
