cc: Remove unused_memory_limit_in_bytes field from GlobalStateThatImpactsTilePriority.

cc: Remove unused_memory_limit_in_bytes field from GlobalStateThatImpactsTilePriority.

This field is not used by the tile manager as it only affects the
resource pool and the tile manager is no longer responsible for
forwarding these changes to the resource pool.

Also removes inappropriate call to SetResourceUsageLimits in
TileManager::SetGlobalStateForTesting.
