Make ++ operator work with strings and binary values (#8017)
This PR makes `++` (the append operator) work with strings and binary
values. Can now do things like:

```bash
〉"a" ++ "b"
ab
〉0x[01 02] ++ 0x[03]
Length: 3 (0x3) bytes | printable whitespace ascii_other non_ascii
00000000:   01 02 03                                             •••
```

Closes #8015.

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`

Better errors when bash-like operators are used (#7241)
# Description

Adds improved errors for when a user uses a bashism that nu doesn't
support.

fixes #7237 

Examples:

```
Error: nu::parser::shell_andand (link)

  × The '&&' operator is not supported in Nushell
   ╭─[entry #1:1:1]
 1 │ ls && ls
   ·    ─┬
   ·     ╰── instead of '&&', use ';' or 'and'
   ╰────
  help: use ';' instead of the shell '&&', or 'and' instead of the boolean '&&'
```

```
Error: nu::parser::shell_oror (link)

  × The '||' operator is not supported in Nushell
   ╭─[entry #8:1:1]
 1 │ ls || ls
   ·    ─┬
   ·     ╰── instead of '||', use 'try' or 'or'
   ╰────
  help: use 'try' instead of the shell '||', or 'or' instead of the boolean '||'
```

```
Error: nu::parser::shell_err (link)

  × The '2>' shell operation is 'err>' in Nushell.
   ╭─[entry #9:1:1]
 1 │ foo 2> bar.txt
   ·     ─┬
   ·      ╰── use 'err>' instead of '2>' in Nushell
   ╰────
```

```
Error: nu::parser::shell_outerr (link)

  × The '2>&1' shell operation is 'out+err>' in Nushell.
   ╭─[entry #10:1:1]
 1 │ foo 2>&1 bar.txt
   ·     ──┬─
   ·       ╰── use 'out+err>' instead of '2>&1' in Nushell
   ╰────
  help: Nushell redirection will write all of stdout before stderr.
```


# User-Facing Changes

**BREAKING CHANGES**

This removes the `&&` and `||` operators. We previously supported by
`&&`/`and` and `||`/`or`. With this change, only `and` and `or` are
valid boolean operators.

# Tests + Formatting

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

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

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

# After Submitting

If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
