    Vulkan: glReadPixels should nearest sample the YUV render target

Vulkan backend uses texture except texelFetch to obtain the YUV image
value for glReadPixels. According to the chroma filter set in the image,
it may apply LINEAR sampling.

* Change this filter to NEAREST inside glReadPixels to get the correct
  pixel values.

* Modify the fragment shader used in glReadPixels to make sure sampling
  from the center of the pixel.

* Add a new end2end test.
