Enhancement

Context: #55184

Starting from TiDB v8.4, the tidb_scatter_region variable supports global scope region scattering. To take advantage of this feature, BR should set this variable to global before creating tables.

Without this configuration, empty tables will not be scattered across the cluster and may instead concentrate on a few TiKV nodes. This uneven distribution increases the likelihood of triggering hotspot issues.
