Tie minor version of all imports to Qt's minor version

This change makes all Qt Quick Controls 2 imports match the current
Qt minor version, which is 12 as of this patch.

It also updates all other Qt Quick imports to match.
This will also make future version bumps easier as all version numbers
in existing code/docs will match.

The following commands were used to verify that no old versions remain:

for i in `seq 0 11`; do git grep "import QtGraphicalEffects.*1.$i$"; done
for i in `seq 0 11`; do git grep "import QtQuick 2.$i$"; done
for i in `seq 0 11`; do git grep "import QtQuick.Layouts 1.$i$"; done
for i in `seq 0 5`; do git grep "import QtQuick.Controls.*2.$i$"; done
for i in `seq 0 11`; do git grep "import QtQuick.Templates 2.$i as T$"; done

[ChangeLog] From Qt 5.12 onwards, all import versions in
Qt Quick Controls 2 follow the same minor version as Qt's
minor version number. For example, the import version for Qt 5.12 is:
"import QtQuick.Controls 2.12".
