Added package for react-native SVG icons

[ValentinaKozlova]

Added package for generation of react-native SVG icons.
1st commit contains copy of react-icons code because majority of it can be reused.
For better readability in other commits I added react-native-specific code.
This PR is for getting early feedback.
Maybe it would be good to put duplicated code in sort of react-common folder.

Issues with current package:

1. Fails while running npm run build:cjs
2. Icon is generated with size in rm which is not suitable for RN

Things to do:

1. Fix issues
2. Add font icons support
3. Move duplicated code to a separate folder

Verification:
Icon generated code looks like this:

import * as React from "react";
import { FluentReactNativeIconsProps } from "../utils/FluentReactNativeIconsProps.types";
import wrapIcon from "../utils/wrapIcon";
import { Path, Svg, Rect, G } from 'react-native-svg';


const AccessTimeFilledIcon = (props: FluentReactNativeIconsProps) => {
  const { fill: primaryFill = 'currentColor', style } = props;
  return <Svg {...props} width="1em" height="1em" viewBox="0 0 20 20" fill="none" xmlns="http://www.w3.org/2000/svg" style={style}><Path d="M...7Z" fill={primaryFill} /></Svg>;
}
export const AccessTimeFilled = /*#__PURE__*/wrapIcon(/*#__PURE__*/AccessTimeFilledIcon, 'AccessTimeFilled');

In RN tester:

As majority of our icons contains only those tags I decided to use regex to change casing

Should these commented lines be removed?

[ValentinaKozlova]

Not for now. Maybe I'll need it later. If not, I'll remove it

Should a "Build React Native library" CI step be added?

Should a "Build React Native library" CI step be added?

Yes, but I thought to add it separately. Next steps can be to move duplicate code to a separate folder, check the generated icons and then build it for RN
