rp2/pendsv: Fix PendSV_Handler dispatch check when threading enabled.
If MICROPY_PY_THREAD is set, PendSV_Handler acquires a mutex and calls the
dispatch functions. If pendsv_schedule_dispatch is called by a higher
priority interrupt while the mutex is acquired by PendSV_Handler it's
possible for the dispatch to not be triggered.
Add a check for dispatch calls at the end of PendSV_Handler once the mutex
has been released.
Fixes issue #18365.
