Subject: Implement am ICommonStateGetter::SetCpuBoostMode (#743)

- Implement am ICommonStateGetter::SetCpuBoostMode according to the RE:

```
signed __int64 __fastcall nn::ICommonStateGetter::SetCpuBoostModeImpl(__int64 this, unsigned int cpu_boost_mode)
{
  if ( cpu_boost_mode > 1 )
  {
    return 0x3F480LL;
  }

  __int64 v2 = *(_QWORD *)(this + 0x38);
  __int64 v3 = *(_QWORD *)(*(_QWORD *)(v2 + 8) + 0x298LL);

  nnLock((_DWORD *)(v3 + 0x104));

  __int64 v5 = *(_QWORD *)(v2 + 0x18);
  bool unk_bool = *(unsigned __int8 *)(v5 + 0x7C);

  *(_DWORD *)(v5 + 0x80) = cpu_boost_mode;

  if (!unk_bool)
  {
    *(_BYTE *)(v5 + 0x7C) = 1;
  }

  wait_condvar(v3 + 0xA8);
  nnUnlock((_DWORD *)(v3 + 0x104));

  return 0LL;
}
```

- Add enum for apm CpuBoostMode
- Add missing values in apm PerformanceConfiguration with some comments.
