do command: Make closure support default parameters and type checking (#12056) 
# Description
Fixes: #11287
Fixes: #11318

It's implemented by porting the similar logic in `eval_call`, I've tried
to reduce duplicate code, but it seems that it's hard without using
macros.

3ee2fc60f9/crates/nu-engine/src/eval.rs (L60-L130)

It only works for `do` command.

# User-Facing Changes
## Closure supports optional parameter
```nushell
let code = {|x?| print ($x | default "i'm the default")}
do $code
```
Previously it raises an error, after this change, it prints `i'm the
default`.

## Closure supports type checking
```nushell
let code = {|x: int| echo $x}
do $code "aa"
```
After this change, it will raise an error with a message: `can't convert
string to int`

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
