Number Formatting: support BigInt and String in additional to Number

[mahnunchik]

Clear and concise description of the problem

Intl.NumberFormat supports Number, BigInt, and String as a number parameter.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/NumberFormat/format

A Number, BigInt, or string, to format. Strings are parsed in the same way as in number conversion, except that format() will use the exact value that the string represents, avoiding loss of precision during implicitly conversion to a number.

Currently only number is supported in vue-i18n library: https://github.com/intlify/vue-i18n-next/blob/fa612d336e603cce237491eca092a7e856e4cb6c/packages/vue-i18n-core/src/components/NumberFormat.ts#L44-L47

Suggested solution

$n method should support the same types of parameter as underlying Intl.NumberFormat.prototype.format() method.

Alternative

No response

Additional context

• BigInt parameter is useful for numbers exceed MAX_SAFE_INT numbers
• String parameter is useful for number with many decimals places.

Any news?

I'm unable to format number like Intl.NumberFormat can:

const number = '123456.78900000000000001';

console.log(new Intl.NumberFormat('en', { maximumFractionDigits: 20 }).format(number));
// 123,456.78900000000000001

hmm 🤔 I would like to support BigInt for NumberFormat, but, vue-i18n uses classic props, which results in a type error. 😭 https://github.com/vuejs/core/issues/5652
