[Android][LWRP] Performance regression when using LWRP settings on an empty scene with some devices using a OpenGL ES 3.0

Package: Scriptable Render Pipeline Lightweight

-

To reproduce:
1. Open the QA's provided project
2. Build and run the sample scene
3. Profile the player
4. Set the Scriptable Render Pipeline Settings file to LWRPAsset
5. Build and run the same SampleScene
6. Profile the player once again

Expected result: Framerate stays the same
Actual result: Framerate gets lower when the LWRP settings are used

  1. Resolution Note:

    We checked and performance is the same of Built-in and LWRP when using the same MSAA settings. When switching to LWRP, the MSAA value in the pipeline asset will overwrite the one in Quality Settings. This is not ideal, but it's not something we can fix in a near future. The MSAA QualitySettings is deeply hooked up for mobile and VR platforms.
