Introduce hold/swipe interaction in submit buttons on Confirmations

[This is a security enhancement]

This proposed change aims to significantly improve the user-friendliness and security of MetaMask Wallet. Feedback and thoughts on this proposal by @witmicko are welcome and appreciated.

****Description****

Currently, MetaMask Wallet uses a "Send" button for initiating transactions. This standard practice, while familiar to users, carries a risk of accidental clicks, leading to unintended transactions. Such mishaps can occur when users are spammed or tricked into displaying a /send app link that is ERC-681 compliant.

e.g.

To mitigate this risk and enhance the user experience, we propose that we transition from the "Send" button to a "Hold/Swipe to Activate" functionality. This would require users to hold the button for a short duration (e.g., 2-3 seconds) before the transaction is initiated. This functionality is already in use for the "Reveal SRP" or "Swap" features in our wallet.

Benefits:

1. **Reduced Risk of Accidental Transactions**: The "Hold or Swipe to Activate" functionality would necessitate a more deliberate action from the user, thereby reducing the likelihood of accidental transactions.
2. **Consistency**: Implementing this change would bring consistency to our wallet's interface, as we already use the "Hold to Activate" functionality for other features.
3. **Enhanced User Experience**: This change would provide users with an additional layer of security and control, potentially enhancing their overall experience with our wallet.

****User Interface****
TBD

Start by reviewing the Confirmations submit flow and the existing hold-to-activate interactions used for Reveal SRP and Swap. The proposal leaves the user interface and exact behavior TBD; done would require an agreed design and applying the hold or swipe interaction to the relevant transaction confirmation actions, with verification that accidental activation is reduced.
