[iOS] Higher memory consumption in Load/Store Bandwidth frame using commandBuffer.Blit()

iOS

-

To reproduce:
1. Open project
2. Build to XCode and runs in a Metal iOS Device.
3. Capture a frame to see only one RenderCommandEncoder generated. Frame Load&Store Bandwidth is around 8MB
4. Open CameraController.cs in the editor and Uncomment Lines of 71 - 76, which adds the blit operation to the commandbuffer
5. Build project to XCode and runs in a Metal iOS Device.
6. Capture a frame to see there are 3 RenderCommandEncoders generated(expected 1). Frame Load&Store Bandwidth is around 80MB

Reproduced: 2017.1.3p4, 2017.2.2p4, 2017.3.2f1, 2017.4.3f1, 2018.1.0f2, 2018.2.0a6
Not reproducible: 2018.2.0a8, 2018.2.0b4

Note:
- fixed in 2018.2 between a6-a8
- tested with:
- iPhone 6S Plus iOS 10.3.2 (Frame Load&Store Bandwidth in 6th step is around 80MB)
- iPhone 7 iOS 11.0 (Frame Load&Store Bandwidth in 6th step is around 35-40MB)
