Make external command substitution works friendly(like fish shell, trailing ending newlines) (#7156)
# Description

As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.

And if the command is executed directly like: `cat tmp`, the result
won't change.

Fixes: #6816
Fixes: #3980


Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.

If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Stdout/Stderr redirection (#7185)

Also, make type output to be more friendly, like `record<>` should just be `record`

And the same to `table<>`, which should be `table`

* simplify code

* don't show signatures for parser keyword

* update comment

* output arg syntax shape as type, so it's the same as describe command

* fix string when no positional args

* update signature body

* update

* add help signature test

* fix arg output format for composed data type like list or record

Add input-output types to $nu.scope.commands (#7105)
* Add input and output types to $nu.scope.commands

This commit changes the schema: instead of

command.signature: table

we now have

command.signatures: list<table>

with one signature for every input-output type pair.

* Represent signatures as a map from input_type to signature

* Sort signature entries

* Drop command name from signature tables

* Don't use "rest" as name of rest parameter; use empty string instead

* Bug fix: was creating records with repeated keys

E.g.
$nu.scope.commands | where name == 'hash sha256' | get signatures.0 | table -e
$nu.scope.commands | where name == 'transpose' | get signatures.0 | table -e

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.
