[blitter] Initialize m_devicePixelRatio to fix crash
When using directfb platform the drawing of some widgets (e.g. Toolbar)
would crash the application.
Pixmap device pixel ratio can be used in QCommonStyle::drawControl() as
a denominator to calculate pixmap width or size. The drawing of some
widgets (e.g. Toolbar) would fail the assertion of a non-zero
denominator.
This commit initializes the device pixel ratio when generating
BlitterClass pixmaps and makes QBlittablePlatformPixmap::metric(
PdmDevicePixelRatio) return devicePixelRatio() instead of 1.
