Add counters for commands processed through the libpq page service API #8089

I was looking for metrics on how many computes are still using protocol version 1 and 2. This provides counters for that as "pagestream" and "pagestream_v2" commands, but also all the other commands. The new metrics are global for the whole pageserver instance rather than per-tenant, so the additional metrics bloat should be fairly small.
