Douglas d702c4605a Increment SHLVL before run_repl() (#14732)
# Description

A follow-on to #14727:

* Instead of using `is-interactive` as the trigger for incrementing
`SHLVL`, this change puts the increment logic just before `run_repl()`
is called.
* Tests are changed to use `-e`
* Moves the `confirm_stdin_is_terminal()` call immediately **after** the
`prerun_cmd` (which executes `--execute (-e) <commandstring>`. The fact
that it was **before** that call seems to be a bug, since the error
message says *"or provide arguments to invoke a script"* even if
`--execute` was used. This change enables REPL testing using `--execute
(-e)`.
* Added a test to ensure `-c` does *not* increment SHLVL.

# User-Facing Changes

`$env.SHLVL` runs before the REPL is started, rather than when
`is-interactive`

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.
