Associate tagged keys with entries so replacements are not evicted
Prevent output caching tags from being lost when updating an existing entry.
Description
If an output cache entry is created with tags and is then replaced, the callback will remove tags which is wrong and would lead to related entries to not be evicted automatically.
Fixes #61524
Customer Impact
Could lead to stale data in cache.
Regression?
Risk
Change is limited to how the entries are tracked, such that less tags are removed. This means more things can be evicted from cache eventually, which is safer (more evicted cache entries is not worse).
Verification
Packaging changes reviewed?
