Deprecate KS macros never used in en-US

When I worked on https://github.com/mdn/yari/issues/1274 I noticed there are a lot more macros that would be considered never-used if you focus on the en-US content alone. For example:

MOZILLA/MDN/content  main ✔
▶ rg -i b2gonlyheader2

MOZILLA/MDN/content  main ✔
▶ cd ../translated-content

MOZILLA/MDN/translated-content  main ✔
▶ rg -i b2gonlyheader2
files/zh-tw/web/api/permissions_api/index.html
9:<p>{{ B2GOnlyHeader2('certified') }}</p>

So, that macro is never used in the en-US content, but it’s used in greater-than-zero places in the translated-content.

What we could do is edit these macros so they’re marked as deprecated and just return an empty string.

Here’s a complete list of macros that exist but are only used in translated-content:

There are four macros used in Japanese translation only. I agree with to remove them and to replace with other expressions. I will ask the l10n-ja community for help in removing them.

Deprecation has been done in #6251 and #6252, now all that’s left is to remove them!
