Migration to CoreBluetoothMock framework

[philips77]

This PR migrates the project from CoreBluetooth to CoreBluetoothMock framework.

Follow commit for step-by-step migration:

1. 9abf667 - Add CoreBluetoothMock dependency using Swift Package Manager (SPM).
2. 1daa48a - Adding Aliases.swift file and fixing compilation errors:
   a. CBCentralManager initialization changed to use CBMCentralManagerFactory.
   b. Applying a change needed if CBPeripheral instances were compared with each other.
3. 98ca20e - Setting initial state of the manager to .poweredOn. By default, the manager is initially disabled.
4. aea1640 - Adding a mock peripheral implementation.

The mocking framework can also be used to render SwiftUI Previews:

1. f86d80a - Mock peripherals will show up on scanner screen just as if run on a Simulator.
2. 5f8e687 - If an instance of CBPeripheral is needed in a Preview, a special CBMPeripheralPreview class can be used.
