[oe] [meta-qt5][PATCH v2 2/2] populate_sdk_qt5.bbclass: Add support for qtcreator-debug

[Otavio Salvador]

This adds a new image feature for easier remote debugging with
QtCreator.

The qtcreator-debug needs to be added as a valid item for image
features and having it inside the populate_sdk_qt5 is too late. User
will see a parser error as OE-Core images does not inherit the classs.
The possible workaround for it is to include it inside layer.conf file
until a kind of "bbclassappend" support is in place.
