I18N: Introduce the Plural_Forms class.

Historically, we've evaluated the plural forms for each language using `create_function()`. This is being deprecated in PHP 7.2, so needs to be replaced.

The `Plural_Forms` class parses the `Plural-Forms` header from the PO file, and internally caches the result of all subsequent plural form tests, allowing it to match the performance of the existing code.

Props rmccue.
Fixes #41562.
