UX: Create a comon error/warning/info label and use it in many places

We have a couple of places which implement the same thing in many different ways, with many different looks: A label with text and error/warning/info icon.
Let's have a central one and use it everywhere.

Some custom implementations:

• Qmake build configuration:
  

• CMake build configuration:
  

• Android options:
  

• Project Wizard:
  

• Project Wizard QDS (see QDS-1346):
  

• Diagnostic Configuration:
