Remove $force argument from WP_Object_Cache::delete()

[ryan]

This was introduced way back in [3086] and hasn't been needed for years.

Sounds good. This was for internal-use-only, I don't think _deprecated_argument() is needed, but let's put a comment somewhere just so we know we'd have to be careful if we ever want to add a third argument here later.

[SergeyBiryukov]

Could we just rename it to $deprecated?

[wonderboymusic]

I am open to any and all suggestions - do whatever you think works.

[wonderboymusic]

also, [27064] didn't post here.

[kovshenin]

Fixed in r27064.

[SergeyBiryukov]

22478.patch​ would probably be more obvious and consistent with how we generally handle deprecated arguments.

I'm fine with [27064] too, so feel free to re-close if we want to remove the argument completely here.

[wonderboymusic]

I have no preference - change however you want

[wonderboymusic]

In 27162:

Rather than removing the 3rd argument in WP_Object_Cache::delete(), mark it as $deprecated.

See [27064].
Props SergeyBiryukov.
Fixes #22478.
