Posible regression - https://github.com/Tinkoff/taiga-ui/pull/1867

I wonder, if with the new mask we should use prefix and postfix from the mask and keep them part of the input, rather than separate DOM elements, what do you think, @splincode @nsbarsukov @vladimirpotekhin ? Things to keep in mind:

1. Right now prefix/postfix are not selectable. Is it good?
2. RTL languages support

I thought about it too. At first glance, putting a prefix / postfix in the input part is a more organic solution.

It would definitely simplify a lot of things.
