stdlib: add test discovery, extract test files (#8443)
# Description

Was original asked here:
https://github.com/nushell/nushell/pull/8405#issuecomment-1465062652
Make it easier to extend standard library with submodules.
(For a new submodule called `xx.nu` the tests can be written in
`test_xx.nu`).
Test discovery is implemented.

# User-Facing Changes

There are no user-facing changes.

# Tests + Formatting

Tests are updated.
There is no `nufmt` now.
