Update HW Manager

[soroushm]

Description

The HW Manager is a singleton class responsible for communicating with a hardware wallet (HW) and providing functionality that the application needs. All communication is event based and working with window.ipc.

Users may connect more than one HW on their PC, Lisk Desktop should provide an ability to select/switch between connected hardware wallet devices .

Acceptance Criteria

• Add required methods to detect, updated, and return the list of connected devices
• Once the HW is selected/connected, we should start reading addresses from HW, make API calls to determine if the account is used, and store used accounts in an array on the HWManager class. Stored account include publicKey, address, deviceID, accountIndex. Store the accounts in the format similar to locally resisted accounts (this part is done in Memoize HW Accounts in HWManager #4767).
• Create getAccounts method to return the list of accounts as generated by the above criteria.
• Selecting/switching between multiple HWs by device ID
• Create GetDeviceList method to return the list of connected devices.
• Retrieve, store and update the list of connected devices on a member in the HWManager class. We should subscribe to HW_CONNECTED and HW_DISCONNECTED events and update the list of connected devices.
• Create a method to sign transactions. Collect all normalizations, and crypto calculation into a utility function. Then use in HWManager.
• Create GetCurrentDeviceInfo which returns HW informations such as brand, model, ID, status (connected, standBy, 'isLoading'). The isLoading state is used to determine if the HWManager is pending a response from the HWManager right after connecting to it.
• Add unit tests

Additional info

The HWManager class should expose the following methods:

• CreateAccount
• GetAccounts
• GetDeviceList
• SelectDevice
• GetDeviceByID
• SignTransaction
• SignMessage
• PresistConnection
• GetCurrentDeviceInfo
