database.hh has large fan-in and therefore can trigger a lot
of recompilations if included. Replace with smaller dependencies.
Closesscylladb/scylladb#21424
The following command had been executed to get the
list of headers that did not contain '#pragma once':
'grep -rnw . -e "#pragma once" --include *.hh -L'
This change adds missing include guard to headers
that did not contain any guard.

Containing utility methods to query data from the local replica.
Intended to be used to read system tables, completely bypassing storage
proxy in the process.
This duplicates some code already found in storage proxy, but that is a
small price to pay, to be able to break some circular dependencies
involving storage proxy, that have been plaguing us since time
immemorial.
One thing we lose with this, is the smp service level using in storage
proxy. If this becomes a problem, we can create one in database and use
it in these methods too.
Another thing we lose is increasing `replica_cross_shard_ops` storage
proxy stat. I think this is not a problem at all as these new functions
are meant to be used by internal users, which will reduce the internal
noise in this metric, which is meant to indicate users not using
shard-aware clients.
