py/mpthread.h: Use strong type for mp_thread_set_state() argument.

This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*.  This matches the return type of
mp_thread_get_state(), which returns the same value.

`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.
