print nushell startup time (#7831)
# Description

This PR shows the startup time and decreases the banner. This startup
time output can be disabled with the `show_banner: false` setting in the
config. This is the startup in debug mode.

On my mac in release mode
```
Startup Time: 368ms 429µs 83ns
```
On my mac without a config as `nu --config foo --env-config foo`
```
Startup Time: 11ms 663µs 791ns
```

I could really go either way on this. If people don't like this change,
we don't have to merge it.

Startup Time

# 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
