Use shader to calculate sample point

The test's sampling point is taking from interpolated varying, the inaccuracy
of interpolation may cause wrong sampling, use gl_FragCoord in fragment
shader to calcuate sample point directly.

Component: OpenGL

Affected tests: KHR-GLES32.core.nearest_edge.offset_*

VK-GL-CTS issue: 2651
