- Shader Precision Model should be changed per profile and not globally

Steps to reproduce:

1. Open Build Profile window (File > Build Profiles)

2. Create a build profile and add a custom player settings (Press Customize player settings)

3. Change Shader Precision Model in Other Settings > Shader Settings

Actual results: 

When changing the Shader Precision Model for a build profile, it's changing globally (for all profiles and for Project Settings > Player Settings)

Expected results: 

The Shader Precision Model should be changed for build profile only
