Create tests/_manual, add Socket tests

[hierophect]

This PR adds a new manual tests folder for scripts that are primarily useful for testing core modules (ie, that do not use libraries and focus on raw API access to a single module). It also adds three tests: Host, Client, and NTP access tests for the Socket module. Future additions to this testing folder should be sorted by module name, matching shared-bindings and common-hal.

Why is there an underscore in the name?

I thought it might be appropriate to distinguish them from the Micropython battery of tests that are run automatically by run-tests. The rest of the tests in that folder are very uniform in style and purpose, and these are different enough that I thought it'd be worth prefixing them.

If anything we could do circuitpy-manual to mimic what we do in py.

Note, I added manual with my audiopwm changes that were merged in already.

That sounds good to me, since there's already a convention there. I'll change this PR to merge the two under that name.

Ok, thanks!
