Superficial changes to script-opt related code

* Rename overly generic ACCESSORS macro with ZEEK_ prefix
* A few places where whitespace was noticeably wrong/distracting
* Minor/obvious reference/move semantics improvements suggested by linter
* Remove unused detail::Scope::Remove(), no need for deprecation
