nu-path crate refactor (#3730)
* Resolve rebase artifacts

* Remove leftover dependencies on removed feature

* Remove unnecessary 'pub'

* Start taking notes and fooling around

* Split canonicalize to two versions; Add TODOs

One that takes `relative_to` and one that doesn't.
More TODO notes.

* Merge absolutize to and rename resolve_dots

* Add custom absolutize fn and use it in path expand

* Convert a couple of dunce::canonicalize to ours

* Update nu-path description

* Replace all canonicalize with nu-path version

* Remove leftover dunce dependencies

* Fix broken autocd with trailing slash

Trailing slash is preserved *only* in paths that do not contain "." or
"..". This should be fixed in the future to cover all paths but for now
it at least covers basic cases.

* Use dunce::canonicalize for canonicalizing

* Alow cd recovery from non-existent cwd

* Disable removed canonicalize functionality tests

Remove unused import

* Break down nu-path into separate modules

* Remove unused public imports

* Remove abundant cow mapping

* Fix clippy warning

* Reformulate old canonicalize tests to expand_path

They wouldn't work with the new canonicalize.

* Canonicalize also ~ and ndots; Unify path joining

Also, add doc comments in nu_path::expansions.

* Add comment

* Avoid expanding ndots if path is not valid UTF-8

With this change, no lossy path->string conversion should happen in the
nu-path crate.

* Fmt

* Slight expand_tilde refactor; Add doc comments

* Start nu-path integration tests

* Add tests TODO

* Fix docstring typo

* Fix some doc strings

* Add README for nu-path crate

* Add a couple of canonicalize tests

* Add nu-path integration tests

* Add trim trailing slashes tests

* Update nu-path dependency

* Remove unused import

* Regenerate lockfile

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
