[1.0] ESP32 - BLE Indications should be sequential

[dhrishi]

Reproduction steps

It can happen that when large amount of data is sent through BLE indications (with lesser MTU, may be) this can cause problems of resource exhaustion at the BLE layer. As indications are acked, the next should be sent once the ack for the previous one is received.

Anything else?

As per the BLE specification:

Indications sent from a server also use a sequential indication-confirmation
protocol. No other indications shall be sent to the same client from this server
until a confirmation PDU has been received.
