AustinandCatalin Patulea 9da0ee9c51 NimBLE-Arduino -> Arduino "BLE" (3.3.x) migration (#10164)
* NimBLE-Arduino -> Arduino "BLE" (3.3.x) migration

* More NimBLE

* Fix Device Name in ATT Read Request (0x2A00).

Device Name is exposed in two places:

- Advertisement data: this is set properly in startAdvertising.
- GATT attribute Device Name (0x2A00). This one is handled internally in NimBLE
  and comes from ble_svc_gap_device_name_set. This is set initially, but then
  BLEDevice::createServer calls ble_svc_gap_init which resets the device name.
  This causes the device to apparently "change name after pairing":

< ACL Data TX:... flags 0x00 dlen 7  #113 [hci0] 14.241149
      ATT: Read Request (0x0a) len 2
        Handle: 0x0003 Type: Device Name (0x2a00)
> ACL Data RX: Handle 2048 flags 0x02 dlen 11             #115 [hci0] 14.269050
      ATT: Read Response (0x0b) len 6
        Value[6]: 6e696d626c65   # "nimble"

Workaround this by setting the device name once again after
BLEDevice::createServer.

* Temporarily lower CORE_DEBUG_LEVEL to INFO to avoid triggering an apparent ESP-IDF Bluetooth bug when re-connecting to Pixel 8 Android devices.

Initial pairing works, but after ESP32 is rebooted, phone fails to reconnect. Meshtastic app shows it as disconnecting immediately. LightBlue shows a more detailed error "Peripheral Connection - Warning: onConnectionStatusChange: status 61" (0x3D - MIC Failure).

Bug report to Espresssif: https://github.com/espressif/esp-idf/issues/18126#issuecomment-4286197744

* Temporarily disable ble_gap_set_data_len, causes crash with Pixel 8 Android reconnect.

Crash looks like this:
  [ 11966][E][BLEAdvertising.cpp:341] setScanResponseData(): ble_gap_adv_rsp_set_data: 22
  [ 11975][E][BLEAdvertising.cpp:1554] start(): Host reset, wait for sync.
  ERROR | ??:??:?? 11 BLE failed to start advertising

Connection seems fast enough even without this. We'll investigate the
reason for the crash and re-enable once it's safe.
