Support binary data to stdin of run-external (#4984)
* Add test for passing binary data through externals

This change adds an ignored test to confirm that binary data is passed
correctly between externals to be enabled in a later commit along with
the fix.

To assist in platform agnostic testing of binary data a couple of
additional testbins were added to allow testing on `Value::Binary` inside
`ExternalStream`.

* Support binary data to stdin of run-external

Prior to this change, any pipeline producing binary data (not detected
as string) then feed into an external would be ignored due to
run-external only supporting `Value::String` on stdin.

This change adds binary stdin support for externals allowing something
like this for example:

  〉^cat /dev/urandom | ^head -c 1MiB | ^pv -b | ignore
  1.00MiB

This would previously output `0.00 B [0.00 B/s]` due to the data not
being pushed to stdin at each stage.

Sanitize arguments to external commands a bit better (#4157)
* fix #4140

We are passing commands into a shell underneath but we were not
escaping arguments correctly. This new version of the code also takes
into consideration the ";" and "&" characters, which have special
meaning in shells.

We would probably benefit from a more robust way to join arguments to
shell programs. Python's stdlib has shlex.join, and perhaps we can
take that implementation as a reference.

* clean up escaping of posix shell args

I believe the right place to do escaping of arguments was in the
spawn_sh_command function. Note that this change prevents things like:

^echo "$(ls)"

from executing the ls command. Instead, this will just print

$(ls)

The regex has been taken from the python stdlib implementation of shlex.quote

Create errors from tables. (#3986)
```
> [
  [          msg,                 labels,                      span];
  ["The message", "Helpful message here", ([[start, end]; [0, 141]])]
] | error make

error: The message
  ┌─ shell:1:1
  │
1 │ ╭ [
2 │ │   [          msg,                 labels,                      span];
3 │ │   ["The message", "Helpful message here", ([[start, end]; [0, 141]])]
  │ ╰─────────────────────────────────────────────────────────────────────^ Helpful message here
```

Adding a more flexible approach for creating error values. One use case, for instance is the
idea of a test framework. A failed assertion instead of printing to the screen it could create
tables with more details of the failed assertion and pass it to this command for making a full
fledge error that Nu can show. This can (and should) be extended for capturing error values as well
in the pipeline. One could also use it for inspection.

For example: `.... | error inspect { # inspection here }`

or "error handling" as well, like so: `.... | error capture { fix here }`

However, we start here only with `error make` that creates an error value for you with limited support for the time being.

Allow environment variables to be hidden (#3950)
* Allow environment variables to be hidden

This change allows environment variables in Nushell to have a value of
`Nothing`, which can be set by the user by passing `$nothing` to
`let-env` and friends.

Environment variables with a value of Nothing behave as if they are not
set at all. This allows a user to shadow the value of an environment
variable in a parent scope, effectively removing it from their current
scope. This was not possible before, because a scope can not affect its
parent scopes.

This is a workaround for issues like #3920.

Additionally, this allows a user to simultaneously set, change and
remove multiple environment variables via `load-env`. Any environment
variables set to $nothing will be hidden and thus act as if they are
removed. This simplifies working with virtual environments, which rely
on setting multiple environment variables, including PATH, to specific
values, and remove/change them on deactivation.

One surprising behavior is that an environment variable set to $nothing
will act as if it is not set when querying it (via $nu.env.X), but it is
still possible to remove it entirely via `unlet-env`. If the same
environment variable is present in the parent scope, the value in the
parent scope will be visible to the user. This might be surprising
behavior to users who are not familiar with the implementation details.

An additional corner case is the the shorthand form of `with-env` does
not work with this feature. Using `X=$nothing` will set $nu.env.X to the
string "$nothing". The long-form works as expected: `with-env [X
$nothing] {...}`.

* Remove unused import

* Allow all primitives to be convert to strings

Add the load-env command (#3484)
* Add the load-env command

load-env can be used to add environment variables dynamically via an
InputStream. This allows developers to create tools that output environment
variables as key-value pairs, then have the user load those variables in using
load-env. This supplants most of the need for an `eval` command, which is
mostly used in POSIX envs for setting env vars.

Fixes #3481
