`EnvironmentRestorer` is an RAII object that will, upon destruction,
restore the previous state of environment variables that it modified.
For example:
```
// ${VAR} has some initial state.
{
EnvironmentRestorer env;
env.SetEnv("VAR", "value");
// ${VAR} now holds "value".
}
// The initial state of ${VAR} has been restored.
```
