We model bind groups as argument buffers, which turn out to be regular MTLBuffers in Metal. On some drivers, creating a MTLBuffer can take a huge amount of time (https://github.com/gpuweb/gpuweb/issues/116#issuecomment-449245367). Instead, we should try to make one big buffer, and use segments of the same buffer for many bind groups (using the "offset" parameter of -[MTLArgumentEncoder setArgumentBuffer:offset] https://developer.apple.com/documentation/metal/mtlargumentencoder/2915777-setargumentbuffer?language=objc
