We split off the evaluation engine part of nu-cli into its own crate. This helps improve build times for nu-cli by 17% in my tests. It also helps us see a bit better what's the core engine portion vs the part specific to the interactive CLI piece.
There's more than can be done here, but I think it's a good start in the right direction.

Continuing on anchoring and improvements on Nu's overall internal commands (#2635).
`move column` sub command has been turned into the command `move` since
we use it to move exclusively columns. Examples added as well.
Fixed it to carry along any anchor locations that might be in place if
table to be moved originates from other sources.
Nu has many commands that allow the nuño to customize behavior such
as UI and behavior. Today, coloring can be customized, the line editor,
and other things. The more options there are, the higher the complexity
in managing them.
To mitigate this Nu can store configuration options as nested properties.
But to add and edit them can be taxing. With column path support we can
work with them easier.
Refactored out most of internal work for summarizing data opening
the door for generating charts from it. A model is introduced
to hold information needed for a summary, Histogram command is
an example of a partial usage. This is the beginning.
Removed implicit arithmetic traits on Value and Primitive to avoid
mixed types panics. The std operations traits can't fail and we
can't guarantee that. We can handle gracefully now since compute_values
was introduced after the parser changes four months ago. The handling
logic should be taken care of either explicitly or in compute_values.
The zero identity trait was also removed (and implementing this forced
us to also implement Add, Mult, etc)
Also: the `math` operations now remove in the output if a given column is not computable:
```
> ls | math sum
──────┬──────────
size │ 150.9 KB
──────┴──────────
```
* Delete unnecessary match
* Use `unwrap_or_else()`
* Whitespace was trim on file save
* Use `map_or_else()`
* Use a default to group all match arms with same output
* Clippy made me do it
