Merge #14608: qt: Remove the "Pay only required fee..." checkbox

Browse source 
a16f44c04 qt: Remove "Pay only required fee" checkbox (Hennadii Stepanov)
8711cc0c7 qt: Improve BitcoinAmountField class (Hennadii Stepanov)

Pull request description:

  Ref #13280
  This PR removes the "Pay only the required fee..." checkbox from the custom transaction fee section in the "Send" tab. Instead, a minimum value will be enforced on the custom fee input box.

  All comments from #13280 are addressed.
