Rename AstTimingControl to AstEventControl (#3425)

IEEE compliant scheduler (#3384) 
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

9abab2c366 Add separate AstInitialStatic node for static initializers 
Static variable initializers run before initial blocks, so use an
explicitly different procedure type for them. This also enables us to
now raise errors for assignments to const variables in initial blocks.

539c9d4c63 Merge alternate 'force'/'release' implementation 
- Add more tests, including for tracing.
- Apply some cleaner, more generic abstractions in the implementation.
- Use clearer AstRelease which is not an assignment.

Generate SELRANGE instead of errors for potentially unreachable code (#2625) (#2754) 
When using a "if" statement inside an always block, part of the code may
be unreachable. This can be used to avoid errors, but it generated an
error, this commit demotes this to a warning. Partly fixes #2625.
