* env_mirror: instruct EnvMirror whether mirrored Envs should be destroyed
The lifecycle rules for Env are frustrating and undocumented. Notably,
Env::Default() should *not* be freed, but any Env instances we created
should be.
Explicitly instruct EnvMirror whether to clean up child Env instances.
Default to false so that we do not affect existing callers.
