Fix edge-line artifacts issue on Mali
Some GMs show edge-line artifacts on Mali at the bottom/right of the canvas.
Change the 'rtAdjustment' uniform precision from 'midiump' to 'highp' if the GPU vendor is ARM.
NOTE: Vertex Shader should have default 'highp' precision, but now we explicit declared some uniform/attribute precision as 'midiump'.
This patch should fix these issues:
Issue 3693: Some GMs produce random artifacts on Mali in MSAA4

Issue 3685: srcmode GM has top/right line artifacts on Mali T604 in MSAA4
