I18N: Introduce an on/off switch for locales where comment number needs to be declined.

When enabled, the switch would override the theme's pseudo-plural `'% Comments'` string with a correct form of `_n( '%s Comment', '%s Comments', $number )`.

Historically, `comments_popup_link()` and `get_comments_number_text()` did not support plural forms and used a pseudo-plural style instead, so some locales were forced to come up with workarounds to display the number of comments in their language correctly.

This change should make those functions more i18n-friendly.

Fixes #13651.
