Enable macOS foreground process handling (#9909)
# Description
Currently, foreground process management is disabled for macOS, since
the original code had issues (see #7068).
This PR re-enables process management on macOS in combination with the
changes from #9693.

# User-Facing Changes
Fixes hang on exit for nested nushells on macOS (issue #9859). Nushell
should now manage processes in the same way on macOS and other unix
systems.

Revert 9693 to prevent CPU hangs (#9893)
# Description

This reverts #9693 as it lead to CPU hangs. (btw, did the revert by hand

)

# 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 -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

automatically

Do not attempt to take control of terminal in non-interactive mode (#9693)
# Description
Fixes a regression from #9681 where nushell will attempt to place itself
into the background or take control of the terminal even in
non-interactive mode.

Using the same
[reference](https://www.gnu.org/software/libc/manual/html_node/Initializing-the-Shell.html)
from #6584:

>A subshell that runs *interactively* has to ensure that it has been
placed in the foreground...

>A subshell that runs *non-interactively* cannot and should not support
job control.

`fish`
[code](54fa1ad6ec/src/reader.cpp (L4862))
also seems to follow this.

This *partially* fixes
[9026](https://github.com/nushell/nushell/issues/9026). That is, nushell
will no longer set the foreground process group in non-interactive mode.

Fix SIGTTIN handling (#9681)
# Description
Due to a typo? in the
[reference](https://www.gnu.org/software/libc/manual/html_node/Initializing-the-Shell.html)
used to implement SIGTTIN handling, nushell will crash when being sent
to the background from within another shell.

For example, currently in bash:
```bash
$ nu -n &
[1] 176058
$ ERROR: failed to SIGTTIN ourselves

[1]+  Exit 1                  nu -n
$
```

Now fixed:
```bash
$ nu -n &
[1] 178788
$ jobs
[1]+  Stopped                 nu -n
$
```

For further reference, this is how
[fish](493cbeb84c/src/reader.cpp (L2571))
does it.

# User-Facing Changes
Bug fix only -- users should now be able to send nushell to the
background.

Use is-terminal crate for now (#9670)
# Description
Until we bump our minimal Rust version to `1.70.0` we can't use
`std::io::IsTerminal`. The crate `is-terminal` (depending on `rustix` or
`windows-sys`) can provide the same.
Get's rid of the dependency on the outdated `atty` crate.
We already transitively depend on it (e.g. through `miette`)

As soon as we reach the new Rust version we can supersede this with
@nibon7's #9550
