esp32: Implement BLE using Nimble from IDF 4.x.

esp32: Run NimBLE on the app core. This prevents issues with concurrent access to the ringbuf. MICROPY_BEGIN_ATOMIC_SECTION is only atomic to the same core. We could address this with a mutex, but it's also not safe to call mp_sched_schedule across cores.

extmod/modbluetooth: Increase maximum connections from 1 to 4. This avoids a confusing ENOMEM raised from gap_advertise if there is currently an active connection. This refers to the static connection buffer pre-allocated by Nimble (nothing to do with MicroPython heap memory).
