OpenGL: Use non-filtering samplers for int/uint texture.

Using a sampler with filtering on int / uint textures makes them
incomplete, causing them to sample black on very conformant drivers.
Each opengl::Sampler is updated to create to GL sampler, a filtering one
and a non-filtering one.

PipelineGL and CommandBufferGL takes advantage of the new
BGLBinding::textureComponentType to know which of the two samplers to
use.
