Unavailable properties for MCU projects

When working on a MCU project, some properties are not available in the property editor even though they exist in Qt Quick Ultralite:

For the Rectangle type:

• radius

For the Image, Text (and StaticText) types (only these specific ones, not for Item or anything else): 

• scale (only since Qt for MCUs 1.3)
• rotation (only since Qt for MCUs 1.3)
• transformOrigin (only since Qt for MCUs 1.3)
