This commit breaks compatibility with Qt 5.4 and earlier versions. It removes the
temporary QObject based TypedArrays and moves the code to use the native
QV4::TypedArray support in Qt 5.5. This allows the implementation now to also
add support for compressed textures and support all getParameter() values.
