New feature: Auto Reconnect (iOS 17+)

[philips77]

This PR adds support for Auto Reconnect feature, added in iOS 17 with CBConnectPeripheralOptionEnableAutoReconnect.

Initialization

Connection with Auto Reconnection enabled is initiated with this flag:

IOS-CoreBluetooth-Mock/Example/nRFBlinky/Models/BlinkyManager.swift

Lines 98 to 105 in 78a577e

	// Enable the Auto Reconnect feature when it's supported.
	if #available(iOS 17.0, *) {
	centralManager.connect(blinky.basePeripheral, options: [
	CBConnectPeripheralOptionEnableAutoReconnect : true,
	])
	} else {
	centralManager.connect(blinky.basePeripheral)
	}

It's supported on iOS 17 and newer.

Besides this flag, a new delegate method was added to iOS API:

optional func centralManager(
    _ central: CBCentralManager,
    didDisconnectPeripheral peripheral: CBPeripheral,
    timestamp: CFAbsoluteTime,
    isReconnecting: Bool,
    error: (any Error)?
)

This callback is ONLY CALLED when there the centralManager(_:didDisconnectPeripheral:error) is not implemented, and only on iOS 17+ (despite what the documentation says).

CoreBluetooth Mock

This PR adds the flag and the above callback to the library. For mock devices, the automatic connection will happen on the first received connectable packet from a mock peripheral.

However, it was not possible to reproduce this (unintended? undocumented? diffcult to use?) behavior of NOT calling this delegate method when the previous centralManager(_:didDisconnectPeripheral:error) was implemented (the library has to implement it, but can't check if the user has implemented it using Swift).

Instead, this delegate method will be called from the library and the default implementation will call the old one. So, if the app implements only the old one, only the old one will be called, like before. If the new and old one is implemented, the old one will not be implemented. This is DIFFERENT from the native behavior, which calls only the new one in such case.
We recommend only using the new one, which in this library will be called also for iOS pre-17.
