Generating mipmaps on RenderTexture with dimensions set to Tex2DArray is very GPU intensive
Reproduction steps:
1. Open the project
2. Open the "test" scene
3. Make sure "Use Mipmap" is enabled on "RT" gameobject
4. Open the GPU profiler
5. Play the scene
Actual result: Generating mipmaps on Tex2DArray uses a lot of GPU time.
Expected result: Generating mipmaps on Tex2DArray occupies less GPU time
Reproduced on: 5.5.0b6, 5.4.1p3
RenderTexture has no dimension variable in 5.3* and 5.2*
