This adds support for making static (ie not on the Python GC heap) soft timers. This can be useful for a board to define some custom background handler, or eventually for BLE/network processing to use instead of systick slots; it will be more efficient using soft timer for this. The main issue with using the existing code for static soft timers is that it would combine heap allocated and statically allocated soft_timer_entry_t instances in the same pairing heap data structure. This would prevent the GC from tracing some of the heap allocated entries (because the GC won't follow pointers outside the heap). This commit makes it so that there are two separate pairing heaps, one for static and one for heap allocated entries. Signed-off-by: Damien George <[email protected]>

After some thought, #7143 is a better implementation. |

Enable BLE where we can. Switch 4MB, non-USB board default partitioning over to a single 2MB firmware bank. Old boards override this setting to keep the same behavior. This also adds alpha support for the ESP32-C2 (aka ESP8684). Fixes micropython#5926 and fixes micropython#7170

This is an alternative to #7143. The implementation here has two separate pairing heaps, one for static timers and one for GC allocated timers. It is simpler.
