We need the higher limit for tessellation shaders and ES 3.2.
Unfortunately this means we are no longer using a packed 64-bit bitset
for the active textures and images. We fallback to using std::bitset.
Also keeps the 64 texture limit if tessellation is not available. The
higher limits was causing timeouts in WebGL tests.
