Texture2DArray.Apply() fails to free texture's system memory after uploading it to GPU
To reproduce:
1. Download and open attached "TestTextureArray2.zip (4.8 MB)" project.
2. Open "main" scene.
3. Enable "LoadTextureArray" object.
4. Build project on any Player (Desktop/Android/iOS).
5. Profile the player with profiler and notice how much total memory uses "Unity" and "GfxDriver".
6. Go back to project and disable LoadTextureArray object.
7. Enable LoadTexture2D object.
8. Repeat steps 4 and 5.
9. Notice the difference in "Unity" memory usage.
Expected result: "Unity" total memory usage should be the same no matter if Loading Texture2Darray or Texture2D.
Actual result: "Unity" total memory usage is significantly bigger when loading texture with Texture2Darray.
Reproduced with: 5.5.3p2, 5.6.1p1, 2017.1.0b5
Reproduced on: Standalone player, iPad Mini 2 (iOS 9.2.1), Samsung SM G903F (GalaxyS5neo)
Notes: Could not test on earlier versions because of shader compilation errors.
