gpu: nvgpu: Remove TPC powergate from safety build

Browse Source 
- Remove non-safe TPC powergate feature from the safety
  build by introducing a new flag:
  CONFIG_NVGPU_TPC_POWERGATE

- Move nvgpu_init_power_gate_gr() under same compile time flag.
  and move HAL function gr_gv11b_powergate_tpc() to tpc_gv11b.c

- Also, remove the negative test scenario and
  usage of tpc_powergate from unit tests
