Construct Records only through checked helpers (#11386)

# Description

Constructing the internals of `Record` without checking the lengths is
bad. (also incompatible with changes to how we store records)

- Use `Record::from_raw_cols_vals` in dataframe code
- Use `record!` macro in dataframe test
- Use `record!` in `nu-color-config` tests
- Stop direct record construction in `nu-command`
- Refactor table construction in `from nuon`

# User-Facing Changes
None

# Tests + Formatting
No new tests, updated tests in equal fashion
