stdlib test runner: implement setup and teardown commands to unit tests (#8776)
# Description

As in other testing frameworks, the `setup` runs before every test case,
and the `teardown` after that. A context can be created in `setup`,
which will be in the `$in` variable in the test cases, and in the
`teardown`. The `teardown` is called regardless of the test is passed,
skipped, or failed.

For example:

```nushell
use std.nu *

export def setup [] {
    log debug "Setup is running"
    {msg: "This is the context"}
}

export def teardown [] {
    log debug $"Teardown is running. Context: ($in)"
}

export def test_assert_pass [] {
    log debug $"Assert is running. Context: ($in)"
}

export def test_assert_skip [] {
    log debug $"Assert is running. Context: ($in)"
    assert skip
}

export def test_assert_fail_skipped_by_default [] {
    log debug $"Assert is running. Context: ($in)"
    assert false
}
```

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.
