Make QtQuick2 compile on QPA

Moved the logic to set pixel size into the font engines to avoid
making the platform plugin interface too complex, and added a function
in QPA to make an isolated font engine based on font data. Currently
none of the QPA back-ends supports it, but it compiles and spits out
a warning if you try to create a QRawFont from data there. This isn't
used in QtQuick2 anyway.
