Angus Gratton 5d8878b582 shared/tinyusb: Only run TinyUSB on the main thread if GIL is disabled.

If GIL is disabled then there's threat of a race condition if some other
code specifically requests USB processing (i.e. to unblock stdio), while
a scheduled TinyUSB callback is already running on another thread.

Relies on the change in the parent commit, where scheduler is restricted
to main thread if GIL is disabled.

Fixes #15390 - "TinyUSB callback can't recurse" exceptions on rp2 when
using _thread module and USB serial I/O.

Adds a unit test for stdin functioning correctly in threads (fails on rp2
port without this fix).

This work was funded through GitHub Sponsors.
