fix: Square payment SDK integration

[kirillzyusko]

📜 Description

Fixed an integration with Square SDK.

💡 Motivation and Context

The current problem is that SQIPTextFieldInputModifier always redirects call to an injected (KCCompositeDelegate) delegate - and it causes infinite loop that eventually leads to a crash 🤷‍♂️

I've tried to find source code of SQIPTextFieldInputModifier but it's closed, and I can not read it.

So far I had two approaches to fix it:

1️⃣ Add state variable and prevent infinite calls

While it solves the problem, it produces other problems - it looks like original delegate methods never gets called and in this case we break Square SDK, so it's not really an option.

2️⃣ Don't set delegate for SQIPTextFieldInputModifier

While it breaks the principle that any focused input will intercept events it makes certain sense:

• seems like Square did such "protection" intentionally;
• Square handler keyboard appearance on their own and it's not possible to use react-native-keyboard-controller component there.

So after thinking a while I decided that we shouldn't inject our delegate for Square SDK inputs. The solution may be not perfect, but for now it totally works. If it causes more issues, then I'll be glad to re-consider the solution with new info in mind.

Closes #896
