Run scripts of any file extension in PATHEXT on Windows (#15611)
# Description
On Windows, I would like to be able to call a script directly in nushell
and have that script be found in the PATH and run based on filetype
associations and PATHEXT.

There have been previous discussions related to this feature, see
https://github.com/nushell/nushell/issues/6440 and
https://github.com/nushell/nushell/issues/15476. The latter issue is
only a few weeks old, and after taking a look at it and the resultant PR
I found that currently nushell is hardcoded to support only running
nushell (.nu) scripts in this way.

This PR seeks to make this functionality more generic. Instead of
checking that the file extension is explicitly `NU`, it instead checks
that it **is not** one of `COM`, `EXE`, `BAT`, `CMD`, or `PS1`. The
first four of these are extensions that Windows can figure out how to
run on its own. This is implied by the output of `ftype` for any of
these extensions, which shows that files are just run without a calling
command anyway.
```
>ftype batfile
batfile="%1" %*
```
PS1 files are ignored because they are handled as a special in later
logic.

In implementing this I initially tried to fetch the value of PATHEXT and
confirm that the file extension was indeed in PATHEXT. But I determined
that because `which()` respects PATHEXT, this would be redundant; any
executable that is found by `which` is already going to have an
extension in PATHEXT. It is thus only necessary to check that it isn't
one of the few extensions that should be called directly, without the
use of `cmd.exe`.


There are some small formatting changes to `run_external.rs` in the PR
as a result of running `cargo fmt` that are not entirely related to the
code I modified. I can back out those changes if that is desired.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Behavior for `.nu` scripts will not change. Users will still need to
ensure they have PATHEXT and filetype associations set correctly for
them to work, but this will now also apply to scripts of other types.

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
