This is a major re-design of the way code is scheduled in Verilator, with the goal of properly supporting the Active and NBA regions of the SystemVerilog scheduling model, as defined in IEEE 1800-2017 chapter 4. With this change, all internally generated clocks should simulate correctly, and there should be no more need for the `clock_enable` and `clocker` attributes for correctness in the absence of Verilator generated library models (`--lib-create`). Details of the new scheduling model and algorithm are provided in docs/internals.rst. Implements #3278
