Implement 'forceable' attribute
...
Using the 'forceable' directive in a configuration file, or the /*
verilator forceable */ metacomment on a variable declaration will
generate additional public signals that allow the specified signals to
be forced/released from the C++ code.

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.

Avoid repeated traversal for SC text sections in emit when not needed
...
Repeatedly traversing whole modules in emit (due to file splitting)
looking for `systemc_* sections can add up to a lot of time on large
designs that have been flattened and need to be split into many files.
Assuming `systemc_* is a rarely used feature, just don't bother if we
don't need to. This gain 9% verilation speed improvement on a large
benchmark.
