Use Record APIs in nu-protocol/nu-engine (#10917)

Browse source 
# Description
Consequences of #10841

This does not yet make the assumption that columns are always
duplicated. Follow the existing logic here

- Use saner record API in `nu-engine/src/eval.rs`
- Use checked record construction in `nu-engine/src/scope.rs`
- Use `values` iterator in `nu-engine/src/scope.rs`
- Use `columns` iterator in `nu_engine::get_columns()`
- Start using record API in `value/mod.rs`
- Use `.insert` in `eval_const.rs` Record code
- Record API for `eval_const.rs` table code
