windows: Implement socket/ssl modules

[stinos]

Socket module is enabled for mingw and msvc builds, mbedtls only for the former; for no particular reason, I can add it there as well if that makes more sense.

As for testing I manually ran the relevant multi_net/net_inet/net_hosted tests and tried the requests module both with and without SSL, and all of that works fine so it's likely that everything is done correctly.

The new multi_net/tcp_recv_timeout.py fails sometimes on ci, likely because one of the recv() calls errors out because the remote disconnected already, which I thought multitest.next() would make sure didn't happen but I probably misunderstood what it does. Someone has an idea for that? I just want the recv calls on both ends to time out.

The test fixes with the numeric values I'm not super happy about, but the only proper way of doing this is to provide common functions to check these errors in a test_helpers module or something like that, and then perhaps implementing a complete errno module for windows which does include all WSAXXX error code, which is a bit much maybe?

This is an automated heads-up that we've just merged a Pull Request
that removes the STATIC macro from MicroPython's C API.

See #13763

A search suggests this PR might apply the STATIC macro to some C code. If it
does, then next time you rebase the PR (or merge from master) then you should
please replace all the STATIC keywords with static.

Although this is an automated message, feel free to @-reply to me directly if
you have any questions about this.

Apart from the STATIC changes, this went rather stale all recent mbedtls changes as well, and the switch from Appveyor to Github Actions; I updated everything now. The 2 mingw standard variant builds currently fail, but there's something weird going on with how Github Actions runs these builds and I'm still looking into that.
