allow --login to be used with nu's --commands parameter (#10253)
# Description

This PR allows the `--login`/`-l` parameter to be used with nushell's
`--commands`/`-c` parameter. When you do this, since you're invoking it
with the `-l` flag, nushell will load your env.nu, config.nu, and
login.nu, in that order. Then it will proceed to run your commands. I
think this provides a better quality of life when you want to run
scripts with your personal config files as a login shell.

Add functions for each Value case (#9736)
# Description
This PR ensures functions exist to extract and create each and every
`Value` case. It also renames `Value::boolean` to `Value::bool` to match
`Value::test_bool`, `Value::as_bool`, and `Value::Bool`. Similarly,
`Value::as_integer` was renamed to `Value::as_int` to be consistent with
`Value::int`, `Value::test_int`, and `Value::Int`. These two renames can
be undone if necessary.

# User-Facing Changes
No user facing changes, but two public functions were renamed which may
affect downstream dependents.

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
```

REFACTOR: move the banner from the rust source to the standard library (#8406)
Related to:
- #8311 
- #8353

# Description
with the new `$nu.startup-time` from #8353 and as mentionned in #8311,
we are now able to fully move the `nushell` banner from the `rust`
source base to the standard library.

this PR
- removes all the `rust` source code for the banner
- rewrites a perfect clone of the banner to `std.nu`, called `std
banner`
- call `std banner` from `default_config.nu`

# User-Facing Changes
see the demo: https://asciinema.org/a/566521

- no config will show the banner (e.g. `cargo run --release --
--no-config-file`)
- a custom config without the `if $env.config.show_banner` block and no
call to `std banner` would never show the banner
- a custom config with the block and `config.show_banner = true` will
show the banner
- a custom config with the block and `config.show_banner = false` will
NOT show the banner

# Tests + Formatting
a new test line has been added to `tests.nu` to check the length of the
`std banner` output.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Add option to not load std-lib. Default tests to not use std-lib (#8833)
this adds a `--no-std-lib` flag. Moves `nu!` to use the `--no-std-lib`.
Adds a new `nu_with_std!` macro for future tests that need the std-lib.

stdlib: make the library a standalone crate (#8770)
# Description
as we now have a prelude thanks to #8627, i'd like to work on the
structure of the library 😋

and i think the first step is to make it a true standalone crate 😏

this PR
- moves all the library from `crates/nu-utils/standard_library/` to
`crates/nu-std/`
- moves the `rust` loading code from `src/run.rs` to
`crates/nu-std/src/lib.rs`

Refactor to support multiple parse errors (#8765)
# Description

This is a pretty heavy refactor of the parser to support multiple parser
errors. It has a few issues we should address before landing:

- [x] In some cases, error quality has gotten worse `1 / "bob"` for
example
- [x] if/else isn't currently parsing correctly
- probably others

# User-Facing Changes

This may have error quality degradation as we adjust to the new error
reporting mechanism.

FEATURE: add the startup time to $nu (#8353)
# Description
in https://github.com/nushell/nushell/issues/8311 and the discord
server, the idea of moving the default banner from the `rust` source to
the `nushell` standar library has emerged 😋

however, in order to do this, one need to have access to all the
variables used in the default banner => all of them are accessible
because known constants, except for the startup time of the shell, which
is not anywhere in the shell...

#### this PR adds exactly this, i.e. the new `startup_time` to the `$nu`
variable, which is computed to have the exact same value as the value
shown in the banner.

## the changes
in order to achieve this, i had to
- add `startup_time` as an `i64` to the `EngineState` => this is, to the
best of my knowledge, the easiest way to pass such an information around
down to where the banner startup time is computed and where the `$nu`
variable is evaluated
- add `startup-time` to the `$nu` variable and use the `EngineState`
getter for `startup_time` to show it as a `Value::Duration`
- pass `engine_state` as a `&mut`able argument from `main.rs` down to
`repl.rs` to allow the setter to change the value of `startup_time` =>
without this, the value would not change and would show `-1ns` as the
default value...
- the value of the startup time is computed in `evaluate_repl` in
`repl.rs`, only once at the beginning, and the same value is used in the
default banner 👌

# User-Facing Changes
one can now access to the same time as shown in the default banner with
```bash
$nu.startup-time
```

# Tests + Formatting
- 🟢 `cargo fmt --all`
- 🟢 `cargo clippy --workspace -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect`
- 🟢 `cargo test --workspace`

Cratification: Test Infrastructure Support Part One (#8335)
startup nushell with no config file or env file...


This PR gives the ability to start up nushell easily with no config or
env config files
simply by passing in

```rust
nu -n
```

or

```rust
nu --no-config-file
```

A bonus is that startup times for nushell decreases FIVE fold...
From about > 50ms to less than < 10ms on average on my mac

This will enable Part II which will hopefully be the ability to
to send this flag into the nu! macro and turn off loading of the config
files...

Remember when config files are enabled the nu-cmd-lang tests fail
because the
commands in the config files are a superset of the commands in
nu-cmd-lang...

In my preliminary tests before by zeroing out the config files the
nu-cmd-lang tests passed...

Independent of the cratification efforts I have always wanted a way
anyway to turn off loading
the config files when starting up nushell... So this accomplishes that
task...

Extract run blocks into functions (#7964)
As usual, Rust optimizes a bit less if more function boundaries are
introduced.
However, in my opinion, being able to comprehend the decision tree beats
a couple of string allocations.
