Make get_env_var return a reference to a Value (#13987)

Browse Source 
# Description
Title says it all, changes `EngineState::get_env_var` to return a
`Option<&'a Value>` instead of an owned `Option<Value>`. This avoids
some unnecessary clones.

I also made a similar change to the `PluginExecutionContext` trait.
