Unify the compare function for sampler and depth stencil

Both sampler and depth stencil include compare function, and we
need to change it to appropriate functions for different backends.
In order to avoid code duplication, we put it into a util file
for every backend, then include that file and call the function
from where we need it.

We can put similar functions which can be shared among different
objects into the util file in future.

Shaobo's patch has already created such a util function for compare
function for sampler. This patch removes the duplicated compare
function in RenderPipeline for depth stencil descriptor, and call
the function in util file instead.
