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. 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.
