8f9644890a167a093d95ecef1f12a20dce1bc581 qt: Remove Transactionview Edit Label Action (Jarol Rodriguez)

Pull request description:

  This PR removes the `Edit Label` action from the `transactionview` context menu. Since the `Edit Label` action will no longer be utilized in the `transactionview`, the `Edit Label` function logic is also removed.

  Among the context menu actions for each transaction in the `transactionview` is the `Edit Label` action.
  While all other actions apply directly to the selected transaction, the `Edit Label` action applies to the selected transaction's address. As documented in issue #209 and [#1168](https://github.com/bitcoin/bitcoin/issues/1168) , this is an "unfortunate" placement for such an action. The current placement creates a confusing UX scenario where the outcome of the action is ambiguous.

  **Example of Ambiguous Behavior:**
  The context menu gives the wrong impression that the `Edit Label` action will edit a `Label` for the specific transaction that has been right-clicked on. This impression can be because all other actions in this menu will relate to the specific transaction and the misconception between `Comment` and `Label`.

  Let's say I wanted to give the transaction selected in the screenshot above a comment of "2-17[17:43]". Given all the context clues, it will be reasonable to assume that the `Edit Label` function will give a label to this transaction. Instead, it edits the `Label` for the address behind this transaction. Thus, changing the `Label` for all transactions associated with this address.

  **Maintaining `Edit Label` Functionality:**
  The action of Editing a Label should instead be reserved for the respective address tables of the `Send` and `Receive` tabs. As documented in this [comment](https://github.com/bitcoin-core/gui/issues/209#issuecomment-780922101), `Edit Label` is currently implemented in the `Send` tab and is missing in the `Receive` tab. A follow-up PR can add the `Edit Label` functionality to the `Receive` tab.
