Angus Gratton cfa55b4ca1 rp2: Fix recursive atomic sections when core1 is active. 
mp_thread_begin_atomic_section() is expected to be recursive (i.e. for
nested machine.disable_irq() calls, or if Python code calls disable_irq()
and then the Python runtime calls mp_handle_pending() which also enters an
atomic section to check the scheduler state).

On rp2 when not using core1 the atomic sections are recursive.

However when core1 was active (i.e. _thread) then there was a bug that
caused the core to live-lock if an atomic section recursed.

Adds a test case specifically for mutual exclusion and recursive atomic
sections when using two threads. Without this fix the test immediately
hangs on rp2.

This work was funded through GitHub Sponsors.
