Compat: BlitTextureToBuffer depth cube texture and refactor

Add implementation to copy depth and stencil cube texture to buffer
using compute shader. In addition, use un-filtering float as
the sampler type for depth texture instead of depth, for all
depth texture copy including cube texture. This is to avoid
glsl textureLod not accepting samplerCubeShadow as param.
