Re-implement aliases (#8123)
# Description

This PR adds an alternative alias implementation. Old aliases still work
but you need to use `old-alias` instead of `alias`.

Instead of replacing spans in the original code and re-parsing, which
proved to be extremely error-prone and a constant source of panics, the
new implementation creates a new command that references the old
command. Consider the new alias defined as `alias ll = ls -l`. The
parser creates a new command called `ll` and remembers that it is
actually a `ls` command called with the `-l` flag. Then, when the parser
sees the `ll` command, it will translate it to `ls -l` and passes to it
any parameters that were passed to the call to `ll`. It works quite
similar to how known externals defined with `extern` are implemented.

The new alias implementation should work the same way as the old
aliases, including exporting from modules, referencing both known and
unknown externals. It seems to preserve custom completions and pipeline
metadata. It is quite robust in most cases but there are some rough
edges (see later).

Fixes https://github.com/nushell/nushell/issues/7648,
https://github.com/nushell/nushell/issues/8026,
https://github.com/nushell/nushell/issues/7512,
https://github.com/nushell/nushell/issues/5780,
https://github.com/nushell/nushell/issues/7754

No effect: https://github.com/nushell/nushell/issues/8122 (we might
revisit the completions code after this PR)

Should use custom command instead:
https://github.com/nushell/nushell/issues/6048

# User-Facing Changes

Since aliases are now basically commands, it has some new implications:

1. `alias spam = "spam"` (requires command call)
	* **workaround**: use `alias spam = echo "spam"`
2. `def foo [] { 'foo' }; alias foo = ls -l` (foo defined more than
once)
* **workaround**: use different name (commands also have this
limitation)
4. `alias ls = (ls | sort-by type name -i)`
* **workaround**: Use custom command. _The common issue with this is
that it is currently not easy to pass flags through custom commands and
command referencing itself will lead to stack overflow. Both of these
issues are meant to be addressed._
5. TODO: Help messages, `which` command, `$nu.scope.aliases`, etc.
* Should we treat the aliases as commands or should they be separated
from regular commands?
6. Needs better error message and syntax highlight for recursed alias
(`alias f = f`)
7. Can't create alias with the same name as existing command (`alias ls
= ls -a`)
	* Might be possible to add support for it (not 100% sure)
8. Standalone `alias` doesn't list aliases anymore
9. Can't alias parser keywords (e.g., stuff like `alias ou = overlay
use` won't work)
	* TODO: Needs a better error message when attempting to do so

A fill command to replace str lpad and str rpad (#7846)
# Description

The point of this command is to allow you to be able to format ints,
floats, filesizes, and strings with an alignment, padding, and a fill
character, as strings. It's meant to take the place of `str lpad` and
`str rpad`.

```
> help fill
Fill and Align

Search terms: display, render, format, pad, align

Usage:
  > fill {flags}

Flags:
  -h, --help - Display the help message for this command
  -w, --width <Int> - The width of the output. Defaults to 1
  -a, --alignment <String> - The alignment of the output. Defaults to Left (Left(l), Right(r), Center(c/m), MiddleRight(cr/mr))
  -c, --character <String> - The character to fill with. Defaults to ' ' (space)

Signatures:
  <number> | fill -> <string>
  <string> | fill -> <string>

Examples:
  Fill a string on the left side to a width of 15 with the character '─'
  > 'nushell' | fill -a l -c '─' -w 15

  Fill a string on the right side to a width of 15 with the character '─'
  > 'nushell' | fill -a r -c '─' -w 15

  Fill a string on both sides to a width of 15 with the character '─'
  > 'nushell' | fill -a m -c '─' -w 15

  Fill a number on the left side to a width of 5 with the character '0'
  > 1 | fill --alignment right --character 0 --width 5

  Fill a filesize on the left side to a width of 5 with the character '0'
  > 1kib | fill --alignment middle --character 0 --width 10
```

fetch -> http get and post -> http post (#7796)
# Updated description by @rgwood

This PR changes `fetch` to `http get` and `post` to `http post`. `fetch`
and `post` are now deprecated. [I surveyed people on
Discord](https://discord.com/channels/601130461678272522/601130461678272524/1065706282566307910)
and users strongly approved of this change.

# Original Description
This PR is related to #2741 and my first pull request in rust :)

Implemented a new http mod to better http support and alias `fetch` and
`post` commands to `http get` and `http post` respectively.

# User-Facing Changes

Users will be able to use HTTP method via http command, for example
``` shell
> http get "https://www.example.com"
<!doctype html>
<html>
...
```

Remove math eval command (#7284)
Reasoning: 

Most missing math commands are implemented with #7258.
The `meval` crate itself declares that it doesn't strive to stringent
standards (https://docs.rs/meval/latest/meval/#related-projects).
For example no particular special casing or transformations are
performed to ensure numerical stability. It uses the same rust `std`
library functions we use or have access to (and `f64`).
While the command call syntax in nushell may be a bit more verbose,
having a single source of truth and common commands is beneficial.
Furthermore the `math` commands can themselves implement broadcasting
over lists (or table columns).

Closes #7073

Removed dependencies:
- `meval`
- `nom 1.2.4` (duplicate)

User-Facing Changes:

Scripts using `math eval` will break. 
We remove a further `eval` like behavior to get results through runtime evaluation (albeit limited in scope)

Tests:

- Updated tests that internally used `math eval`.
- Removed one test that primarily used `math eval` to obtain a result from `str join`

Rename all?, any? and empty? (#6464)
Rename `all?`, `any?` and `empty?` to `all`, `any` and `is-empty` for sake of simplicity and consistency.

- More understandable for newcomers, that these commands are no special to others.
- `?` syntax did not really aprove readability. For me it made it worse.
- We can reserve `?` syntax for any other nushell feature.

Deprecate hash base64, extend decode and add encode commands (#5863)
* feat: deprecate `hash base64` command

* feat: extend `decode` and `encode` command families

This commit
- Adds `encode` command family
- Backports `hash base64` features to `encode base64` and `decode base64` subcommands.
- Refactors code a bit and extends tests for encodings
- `decode base64` returns a binary `Value` (that may be decoded into a string using `decode` command)

* feat: add `--binary(-b)` flag to `decode base64`

Default output type is now string, but binary can be requested using this new flag.
