Metal: Fix Intel's LOD clamp and blit shader's filtering. 1. Setting max LOD clamp = FLT_MAX via setSamplerState caused mipmap tests failure on Intel. It always picked wrong mipmap level during texture sampling. Fix: Use value from SamplerState::getMaxLod() instead. 2. Also set default linear filtering for blit shader's sampler. Previously there was no sampler set for this shader. It caused black fragments on Intel. This CL is a prerequisite for enabling end2end tests on Intel & Metal.
