Botond Dénes 555cfbcd38 Merge 'treewide: replace deprecated smp::count and smp::all_cpus() with new APIs' from Avi Kivity ...

Replace all uses of the deprecated seastar::smp::count with this_smp_shard_count() and smp::all_cpus() with this_smp_all_shards() across the ScyllaDB codebase (seastar submodule untouched).

Both replacement functions require a reactor thread context. All call sites were verified to run on reactor threads.

Notable cases:
- dht/token-sharding.hh: this_smp_shard_count() is used as a default parameter value. This is safe since all callers are on reactor threads, but the expression is now evaluated at each call site rather than being a reference to a global variable.
- service/storage_service.hh, locator/abstract_replication_strategy.hh, ent/encryption/encryption.cc: used in default member initializers and constructor member-init-lists. Objects are always constructed on reactor threads.
- schema_builder: sometimes called from BOOST_AUTO_TEST_CASE without a reactor. Added pre-patch that makes the implicit shard count parameter implicit and pass 1 in those cases.

Not changed:
- scylla-gdb.py: reads smp::count as a GDB symbol (no reactor context).
- Python test files: only reference smp::count in comments/strings.

No backport: the Seastar commit that deprecated these function hasn't (and won't) make its way into any release branches (and the warnings are cosmetic anyway)

Closes scylladb/scylladb#29990

* github.com:scylladb/scylladb:
  treewide: replace deprecated smp::count and smp::all_cpus() with new APIs
  scylla-gdb: read shard count from smp::_this_smp instead of smp::count
  schema_builder: make shard_count an explicit constructor parameter
