Qt already supports high DPI icons using the “@nx” approach, where the
device pixel ratio that the image was designed for is in the file
name. However, our implementation of the freedekstop.org Icon Theme
specification did not support the Scale directory key:
https://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html#directory_layout
This meant that users creating icons via QIcon::fromTheme() did not
get high DPI support. This patch fixes that.
[ChangeLog][QtGui][QIcon] Implemented support for Scale directory key
according to Icon Theme Spec. Icons created via QIcon::fromTheme()
now have high DPI support by specifying the Scale in the appropriate
entry of the relevant index.theme file.

Use the new qtConfig macro in all pro/pri files.
This required adding some feature entries, and adding
{private,public}Feature to every referenced already existing entry.

This made sense only for Symbian where there was a special
CFbsBitmap-based backend present and it was used from the
Symbian-specific VG and GL pixmap implementations.
The generic version is merely a useless wrapper over QImage and is not
in use anywhere in the codebase.
