Making nushell works better with external args which surrounded by backtick quotes (#13910) ...

# Description
Fixes: #13431
Fixes: #13578

The issue happened because nushell thinks external program name and
external arg with totally same rule. But actually they are a little bit
different.
When parsing external program name, backtick is a thing and it should be
keeped.
But when parsing external args, backtick is just a mark that it's a
**bareword which may contain space**. So in this context, it's already
useless.

# User-Facing Changes
After the pr, the following command will work as intended.
```nushell
> ^echo `"hello"`
hello
```

# Tests + Formatting
Added 3 test cases.
