Found while investigating #25021

ElectronBrowserMainParts has a periodic timer that is used to trigger GC once a minute even on an idle system. While one wakeup per minute isn't bad, it's also been in there [since 2014](https://github.com/electron/electron/commit/4dd78480846557370dd53789d50e6cb0d6a81bcd) and may or may not still be necessary. It might be worth seeing what happens to memory overhead if this is disabled and/or triggered with a different mechanism.

```c++
  // Start idle gc.
  gc_timer_.Start(
      FROM_HERE, base::TimeDelta::FromMinutes(1),
      base::Bind(&v8::Isolate::LowMemoryNotification,
                 base::Unretained(js_env_->isolate())));
```
