srcu: Add boot-time control over srcu_node array allocation



This commit adds an srcu_tree.convert_to_big kernel parameter that either
refuses to convert at all (0), converts immediately at init_srcu_struct()
time (1), or lets rcutorture convert it (2).  An addition contention-based
dynamic conversion choice will be added, along with documentation.
