string | fill counts clusters, not graphemes; and doesn't count ANSI escape codes (#8134)
Enhancement of new `fill` command (#7846) to handle content including
ANSI escape codes for formatting or multi-code-point Unicode grapheme
clusters.
In both of these cases, the content is (many) bytes longer than its
visible length, and `fill` was counting the extra bytes so not adding
enough fill characters.

# Description

This script:
```rust
# the teacher emoji `\u{1F9D1}\u{200D}\u{1F3EB}` is 3 code points, but only 1 print position wide.
echo "This output should be 3 print positions wide, with leading and trailing `+`"
$"\u{1F9D1}\u{200D}\u{1F3EB}" | fill -c "+" -w 3 -a "c"

echo "This output should be 3 print positions wide, with leading and trailing `+`"
$"(ansi green)a(ansi reset)" | fill -c "+" -w 3 -a c
echo ""
```

Was producing this output:
```rust
This output should be 3 print positions wide, with leading and trailing `+`
🧑‍🏫

This output should be 3 print positions wide, with leading and trailing `+`
a
```

After this PR, it produces this output:
```rust
This output should be 3 print positions wide, with leading and trailing `+`
+🧑‍🏫+

This output should be 3 print positions wide, with leading and trailing `+`
+a+
```
# User-Facing Changes

Users may have to undo fixes they may have introduced to work around the
former behavior. I have one such in my prompt string that I can now
revert.

# Tests + Formatting

Don't forget to add tests that cover your changes.
-- Done

Make sure you've run and fixed any issues with these commands:

- [x] `cargo fmt --all -- --check` to check standard code formatting
(`cargo fmt --all` applies these changes)
- [x] `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- [x] `cargo test --workspace` to check that all tests pass

# After Submitting

`fill` command not documented in the book, and it still talks about `str
lpad/rpad`. I'll fix.

Note added dependency on a new library `print-positions`, which is an
iterator that yields a complete print position (cluster + Ansi sequence)
per call. Should this be vendored?

Make to text stream ListStreams (#7577)
This PR changes `to text` so that when given a `ListStream`, it streams
the incoming values instead of collecting them all first.

The easiest way to observe/verify this PR is to convert a list to a very
slow `ListStream` with `each`:
```bash
ls | get name | each {|n| sleep 1sec; $n} | to text
```
The `to text` output will appear 1 item at a time.

Revert "into cellpath command (#7417)" (#7523)
This reverts commit f0e93c2fa9 (PR #7417).

I'm currently [working on improving cell
paths](https://github.com/nushell/nushell/issues/7498#issuecomment-1356834798),
and I realized that I would need to make several improvements to `into
cellpath` along the lines of Jakub's comment here:
https://github.com/nushell/nushell/pull/7417#issuecomment-1345264955

I don't think `into cellpath` is quite ready for prime-time, and I'd
like to remove it before the upcoming release.

in for, loop, while, auto print final value in each iteration (#7433)
# Description

Fixes: #7404 
Fixes: #7402 

## About change
In `eval_block`, all pipelines(or called statements?) result will be
printed except the last one, the last one is returned by `eval_block`
function.

So if we want to print the last statement in eval block, we just need to
print that value.

### while

into cellpath command (#7417)
# Description

Address part of feature request #7337, add a small command `into
cellpath` to allow string -> cellpath auto-conversion, with this change,
we could run

```
let p = 'ls.use_ls_colors'
$env.config | upsert ($p | nito cellpath) false
```

Note - This pr only covers `String` -> `CellPath`, any other conversions
should be considered as expected?

New commands: break, continue, return, and loop (#7230)
# Description

This adds `break`, `continue`, `return`, and `loop`.

* `break` - breaks out a loop
* `continue` - continues a loop at the next iteration
* `return` - early return from a function call
* `loop` - loop forever (until the loop hits a break)

Examples:
```
for i in 1..10 {
    if $i == 5 {
       continue
    } 
    print $i
}
```

```
for i in 1..10 {
    if $i == 5 {
        break
    } 
    print $i
}
```

```
def foo [x] {
    if true {
        return 2
    }
    $x
}
foo 100
```

```
loop { print "hello, forever" }
```

```
[1, 2, 3, 4, 5] | each {|x| 
    if $x > 3 { break }
    $x
}
```

- Move the `database` feature from `plugin` to `default`
- Rename the `database` feature to `sqlite`
- Remove `--features=extra` from a lot of scripts etc. 
- No need to specify this, the `extra` feature is now the same as the

Limited mutable variables (#7089)
This adds support for (limited) mutable variables. Mutable variables are created with mut much the same way immutable variables are made with let.

Mutable variables allow mutation via the assignment operator (=).

❯ mut x = 100
❯ $x = 200
❯ print $x
200

Mutable variables are limited in that they're only tended to be used in the local code block. Trying to capture a local variable will result in an error:

❯ mut x = 123; {|| $x }
Error: nu::parser::expected_keyword (link)

  × Capture of mutable variable.

The intent of this limitation is to reduce some of the issues with mutable variables in general: namely they make code that's harder to reason about. By reducing the scope that a mutable variable can be used it, we can help create local reasoning about them.

Mutation can occur with fields as well, as in this case:

❯ mut y = {abc: 123}
❯ $y.abc = 456
❯ $y

On a historical note: mutable variables are something that we resisted for quite a long time, leaning as much as we could on the functional style of pipelines and dataflow. That said, we've watched folks struggle to work with reduce as an approximation for patterns that would be trivial to express with local mutation. With that in mind, we're leaning towards the happy path.

Filter out empty glob patterns to "glob" command (#6707)
* Filter out empty glob patterns

An empty argument to the "glob" command will now produce an empty result.
Working towards nushell/nushell#6653.

* Run `cargo fmt --all`

Just autoformatted the repo so that CI passes and we have a consistent code
format across modules.

* Treat empty glob argument as error

The glob command will now report an empty string argument as an error instead
of silently ignoring it.

See https://github.com/nushell/nushell/pull/6707#discussion_r993345013.

* Add tests for glob command

Two small tests for the glob command, one to check that the empty string errors
it, and another to sanity check the '*' glob, have been added.

* Rename glob sanity check star test
