This commit separates the single `ROUTER_UPGRADE_THRESHOLD` into two distinct concepts: a local threshold for role transitions (used by a REED deciding when to upgrade) and a leader threshold (used by the Leader deciding whether to accept a router upgrade request). This prepares for adding support for a new Router Config feature, where the local threshold can be changed while the threshold used when the device acts as a leader must remain the spec-defined value. To preserve backward compatibility with existing tests and tools, `otThreadSetRouterUpgradeThreshold` continues to set both thresholds simultaneously. Several Nexus test scenarios have been updated to explicitly set the new leader threshold alongside the local router threshold.
