Revolut account should accept only phone number

[beingindot]

Fixes #3728
Till now we used to accept email or phone number
Now we are accepting only phone number in input though
for display we will provide backward compatibility.

Based on the country selected, we will validate the given phone number input.

Added list of countries accepted from official revolut website

NACK

I tested it on Regtest and when switching the country in the combobox the validation is not updated. See screenshots below.

When I switch the country to German the validation condition should be fulfilled, but is still showing the Austrian country code error message

Now I have added updateAllInputsValid() from combobox action event. that triggers validation and it enables save new account.

but the error message around text field is not clearing on its own. only after we press tab it clears. I tried to use accountIdInputTextField.resetValidation() but not working so far. may be that's an existing bug? pls provide suggestions.

resetValidation

It has to be used similar as in the Bankform

holderNameInputTextField.resetValidation();
holderNameInputTextField.validate();

Tested it on Regtest and it is working now as expected.
