E2E test support for HW wallet support -> implementation (Ledger)

[angelcheung22]

Add validation for the Ledger and HW wallet support in mobile (and extension) within the E2E tests?
In the past we've discussed the potential of using software emulators (existing or custom) to mock the responses from the device as needed at the URL or library level.

We can try mock @ledgerhq/react-native-hw-transport-ble to bypass the bluetooth communication. and then we can try to see how to do it in e2e tests. the only downside is if library upgrade, we may need to change the mock again to refect the library API change.
