Add render pass color and depth stencil attachment descriptor

Browse Source 
This patch is the first one of the descriptorization of render pass. In
this patch we add support of RenderPassColorAttachmentDescriptor
and RenderPassDepthStencilAttachmentDescriptor to
RenderPassDescriptorBuilder.

This patch also adds StoreOp to render pass color and depth stencil
attachment descriptor.

RenderPassDescriptorBuilder will be completely removed in the next
patch.
