Vulkan: Fix rotation of interpolateAtOffset
interpolateAtOffset's offset was multiplied by flipXY*rotationMatrix,
which is a vector. This was unable to actually apply rotation to the
offset. The multiplier is changed to a matrix.
Can be tested by running interpolate_at_offset*default_framebuffer tests
in deqp gles3.1 together with pre-rotation:
./angle_deqp_gles31_tests
--deqp-case=dEQP.GLES31/functional_shaders_multisample_interpolation_interpolate_at_offset_no_qualifiers_default_framebuffer
--emulated-pre-rotation=90
