Fetch command fee for token transfer and validator registration

Description

For each command (transaction) implement command fee logic to fetch the fees required using generic endpoint invoke.

The following commands require command fee:

Token transfer and Cross chain token transfer require initialization fee
Register validator command require command fee

As a result the fee value should look like:

[
  { value: 10523000, type: 'total' }, //  The value of commandFee is added to the total value
  { value: 23000, type: 'minFee' },
  { value: 500000, type: 'commandFee' },
]

If an account has a zero balance and its nonce is zero it needs to be initialized You can retrieve commandFee (e.g token transfer initialization fee) using the invoke method from Lisk Service. Simply send a WS request as

{
  "endpoint" : "token_getInitializationFees",
  "params": {} // Empty
}

Acceptance criteria

This hook should be generic so that we can reuse this hook for other command fee in the future
- Accept command name, endpointName, endpointParams as input for this hook, and return the value from invoke proxy endpoint
The command fee should be retrieved from Lisk Service
The fee should be incorporated in the total value and as a dedicated component
Sufficient unit test to cover the additional logic is desired
Adapt token transfer, cross chain token transfer and register validator form to use the above created hook to compute command fee
Fix number of empty signature calculation for multisignature groups.

Additional information

Enhancing the hook created by #4716 , we should use fetch the command fee and incorporate it in the fee values. As mentioned, the value of command fee is defined by the blockchain developer, and no calculation is involved in it. We should merely fetch it from Lisk Service and add it:

To the total fee value
As a dedicated fee component
