Remove invalid endpoint composition from lighting-app (#27133)

Problem:
- lighting-app example has Scenes and Groups clusters on Endpoint 0, which is invalid.

Fixes:
- Remove clusters that don't belong on Endpoint 0
  - LevelControl
  - OnOff
  - Groups
  - Scenes

Testing done:
- TC_RR_1_1 still passes
- TC_LVL_2_1 still passes
