if --no-config-file(-n) is passed, do not load config files with -c (#9286)
# Description

I noticed recently these timing discrepancies. I was thinking they would
be nearly identical but they were not.
```
> nu --no-std-lib -n -c "$nu.startup-time"
13ms 686µs 209ns
> nu --no-std-lib -n
> $nu.startup-time
2ms 520µs 416ns
```
My research showed that if `-n` was passed with `-c`, then the `-n` was
essentially being ignored. This PR corrects that.

Also worthy of understanding, if `nu -c "some command"` is passed, the
default env file is always loaded. I believe that's on purpose so that a
NU_LIB_DIRS env is available.

## After this PR (on a different system)
```
> nu --no-std-lib -n -c "$nu.startup-time"
6ms 688µs 600ns
> nu -n --no-std-lib
> $nu.startup-time
6ms 661µs 800ns
```

# 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 -- crates/nu-std/tests/run.nu` to run the tests for the
standard library

> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr

Nushell REPL

This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.

Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
