Remove unnecessary work from ps (nushell#3407)

The ps plugin has an unnecessary call to `std::thread::sleep(500ms)` that
delays runtime by 500ms. Additionally, there is a call to
`sysinfo::SystemExt::refresh_process`, which is not required as the previous
call to sysinfo::SystemExt::refresh_all handles the "refresh" of all processes
without a need to do this individually. Combining both of these improvements
means that running ps runs nearly instentaneously.

Fixes nushell#3402

Extract .nu-env tests and more granularity (nushell#3078)

The autoenv logic mutates environment variables in the running session as
it operates and decides what to do for trusted directories containing `.nu-env`
files. Few of the ways to interact with it were all in a single test function.

We separate out all the ways that were done in the single test function to document
 it better. This will greatly help once we start refactoring our way out from setting
 environment variables this way to just setting them to `Scope`.

This is part of an on-going effort to keep variables (`PATH` and `ENV`)
in our `Scope` and rely on it for everything related to variables.

We expect to move away from setting (`std::*`) envrironment variables in the current
running process. This is non-trivial since we need to handle cases from vars
coming in from the outside world, prioritize, and also compare to the ones
we have both stored in memory and in configuration files.

Also to send out our in-memory (in `Scope`) variables properly to external
programs once we no longer rely on `std::env` vars from the running process.

update mock table for easier table testing (nushell#3065)
