Subject: [PATCH] Update display dim configuration

To extend battery life, modify the display dim configuration to
enter the dimming state more aggressively. The screen should dim at
minimum(20 seconds, timeout * 0.33) before the screen actually timing out.

     Screen timeout (secs) | Dim duration before | Dim duration After
              15                    3                      4.95
              30                    6                      9.9
              60                    7                     19.8
             120                    7                     20
             300                    7                     20
             600                    7                     20

Bug: 315246849
Flag: EXEMPT resource only update
Test: Build & Verify the dim duration with each setting.
