Implement delete_matched

[julianrubisch]

as per https://api.rubyonrails.org/classes/ActiveSupport/Cache/Store.html#method-i-delete_matched

[oldmoe]

Delete matched would require having the regex SQLite extension installed, maybe we can detect it and run the matcher only if it exists otherwise return a proper error message. The other option is to try and bundle the extension with Litestack (tricky but probably doable)

FYI rails/rails#50443 (comment)

looks like delete_matched could be deprecated in 7.2 and removed in 8.0 so probably best to wait for this issue to resolve before moving forward on that

Plenty of cache stores don't have this method. Is there really a need in that?

[julianrubisch]

I agree that if it's deprecated there's no need implementing it. FWIW I always found it handy when developing locally.
