This patch removes RenderPassDescriptorBuilder completely from Dawn. With this patch, RenderPassDescriptor is a structure instead of a Dawn object, and all the checks in RenderPassDescriptorBuilder are moved into CommandEncoder.cpp. This patch also updates the helper functions and structures related to RenderPassDescriptor because RenderPassDescriptor is no longer an object but a structure with members in pointers.
