Christian Schwarz 3322b6c5b0 page cache: metrics: add page content kind dimension (#5373) ...

The TaskKind dimension added in #5339 is insufficient to understand what
kind of data causes the cache hits.

Regarding performance considerations: I'm not too worried because we're
moving from 3 to 4 one-byte sized fields; likely the space now used by
the new field was padding before. Didn't check this, though, and it
doesn't matter, we need the data.

What I don't like about this PR is that we have an `Unknown` content
type, and I also don't like that there's no compile-time way to assert
that it's set to something != `Unknown` when calling the page cache.
But, this is what I could come up with before tomorrow’s release, and I
think it covers the hot paths.
