Cache-Tag header limit is incorrect

Problem/Motivation

The Cache-Tag header is currently limited to 255 bytes:
https://git.drupalcode.org/project/cloudflare/-/blob/9aa28e567aa9124e985...

Upon further investigation, it looks like this limit is not used and every header value is hashed

@todo Remove this wrapper once CloudFlare supports 16k headers.

https://git.drupalcode.org/project/cloudflare/-/blob/9aa28e567aa9124e985...

Cloudflare now allows headers up to 16KB

Individual tags don’t have a maximum length, but the aggregate Cache-Tag HTTP header cannot exceed 16 KB after the header field name, which is approximately 1000 unique tags. Length includes whitespace and commas, but not the header field name.
