Allow filesystem commands to access files with glob metachars in name (#10694)

Browse source 
(squashed version of #10557, clean commit history and review thread)

Fixes #10571, also potentially: #10364, #10211, #9558, #9310,


# Description
Changes processing of arguments to filesystem commands that are source
paths or globs.
Applies to `cp, cp-old, mv, rm, du` but not `ls` (because it uses a
different globbing interface) or `glob` (because it uses a different
globbing library).

The core of the change is to lookup the argument first as a file and
only glob if it is not. That way,
a path containing glob metacharacters can be referenced without glob
quoting, though it will have to be single quoted to avoid nushell
parsing.

Before: A file path that looks like a glob is not matched by the glob
specified as a (source) argument and takes some thinking about to
access. You might say the glob pattern shadows a file with the same
spelling.
```
> ls a*

> ## Note -- a[bc]d *not* copied, and seemingly hard to access.
> cp --verbose 'a\[bc\]d' dest
Error:   × No matches found
   ╭─[entry #33:1:1]

> #.. but is accessible with enough glob quoting.
> cp --verbose 'a[[]bc[]]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
```
Before_2: if file has glob metachars but isn't a valid pattern, user
gets a confusing error:

```
> touch 'a[b'
> cp 'a[b' dest
Error:   × Pattern syntax error near position 30: invalid range pattern
   ╭─[entry #13:1:1]
 1 │ cp 'a[b' dest
   ·    ──┬──
   ·      ╰── invalid pattern
   ╰────
```

After: Args to cp, mv, etc. are tried first as literal files, and only
as globs if not found to be files.

```
> cp --verbose 'a[bc]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
> cp --verbose '[a][bc]d' dest
copied /home/bobhy/src/rust/work/r4/abd to /home/bobhy/src/rust/work/r4/dest/abd
copied /home/bobhy/src/rust/work/r4/acd to /home/bobhy/src/rust/work/r4/dest/acd
```
After_2: file with glob metachars but invalid pattern just works.
(though Windows does not allow file name to contain `*`.).

```
> cp --verbose 'a[b' dest
copied /home/bobhy/src/rust/work/r4/a[b to /home/bobhy/src/rust/work/r4/dest/a[b
```

So, with this fix, a file shadows a glob pattern with the same spelling.
If you have such a file and really want to use the glob pattern, you
will have to glob quote some of the characters in the pattern. I think
that's less confusing to the user: if ls shows a file with a weird name,
s/he'll still be able to copy, rename or delete it.

# User-Facing Changes
Could break some existing scripts. If user happened to have a file with
a globbish name but was using a glob pattern with the same spelling, the
new version will process the file and not expand the glob.

# 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` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
-->
