feat(input): Add number input localization utility

[yasincaliskan]

Decription

• numberToString utility has added. Locale parameter is "en" as default.
• If shouldFormatToLocaleString is true, numberToString function trigger and return the converted value.
• Integer part corverts with before dot operator.

This may help: https://github.com/globalizejs/globalize/blob/master/doc/api/number/number-parser.md but I think we will need to strict the locales.

This answer seems promising. It references this: https://observablehq.com/@mbostock/localized-number-parsing

Thank you for your suggestions!

• I think we shouldn't remove shouldFormatToLocaleString prop. Because we can use NumberInput for different purposes like phone number or ID. And we can add a locale prop but if the user doesn't pass this prop, we can use the system locale as default. I don't think it will cause any problem.
• Intl.NumberFormat is working fine but format method assumes that taking like 123456.05 number. formatToParts method is very useful but I couldn't combine this method with our RegExp yet. I guess there is some weird stuff 🤔
• I believe that, if we have the proper DECIMAL_NUMBER_SEPARATOR and THOUSANDTHS_SEPARATOR we can handle with numberToString function. Because I think so only Intl.NumberFormat not enough.

Looks like working well with your help. Thank you @edizcelik 🎉

But there is one more thing. We should think of the following replace scope for other locales. It's working fine with only0123456789.

let parsedNumber = value
.replace(new RegExp(NOT_NUMBER_OR_DECIMAL_POINT_REGEX), "")
...

It couldn't work for any different number of characters. (see last story example) Have you an idea for this?
