feat(table): add 'double' table mode (#16013)

Browse Source 
# Description

Add 'double' table mode, that is similar to `compact_double` but with
left and right border lines. This is similar to how there exist both
`single` and `compact`, but there is no `double` to compliment
`compact_double`. Printing `[ { a: 1, b: 11 }, { a: 2, b:12 } ]` looks
like this:

```
╔═══╦═══╦════╗
║ # ║ a ║ b  ║
╠═══╬═══╬════╣
║ 0 ║ 1 ║ 11 ║
║ 1 ║ 2 ║ 12 ║
╚═══╩═══╩════╝
```

The implementation is mostly a one-to-one of #15672 and #15681.

# User-Facing Changes

New value `double` to set as `$env.config.table.mode`.

# Tests + Formatting

Tests are added following the example of adding 'single' mode.
