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...
