Move QQuickTextDocumentWithImageResources out of qquicktext_p_p.h

QQuickTextDocumentWithImageResources was autotest-exported in b63185.
The problem is that the QQuickLabel in qtquickcontrols2 inherits
QQuickText, and therefore includes the private header. An autotest-
exported class with Q_OBJECT macro leads to a linking error:

qquickcontrol.obj : error LNK2019: unresolved external symbol "public: static struct TestNamespace::QMetaObject const TestNamespace::QQuickTextDocumentWithImageResources::staticMetaObject" (?staticMetaObject@QQuickTextDocumentWithImageResources@TestNamespace@@2UQMetaObject@2@B) referenced in function "public: static class TestNamespace::QString __cdecl TestNamespace::QQuickTextDocumentWithImageResources::tr(char const *,char const *,int)" (?tr@QQuickTextDocumentWithImageResources@TestNamespace@@SA?AVQString@2@PBD0H@Z)
qquicklabel.obj : error LNK2001: unresolved external symbol "public: static struct TestNamespace::QMetaObject const TestNamespace::QQuickTextDocumentWithImageResources::staticMetaObject" (?staticMetaObject@QQuickTextDocumentWithImageResources@TestNamespace@@2UQMetaObject@2@B)
