This commig refactors the message-deletion modal and reuses it for case of removing
the entire message and trying to send it, which should trigger removal flow instead.
Fixvector-im/element-web#18873
In case where we had a very long message the experience of going between
messages to see the full quote isn't very nice on desktop, therefore this commit
adds a button with additional hotkey to normalize the experience a bit.
