In non-static contexts like class objects or stack frames, the use of
global trigger evaluation is not feasible. The concept of dynamic
triggers allows for trigger evaluation in such cases. These triggers are
simply local variables, and coroutines are themselves responsible for
evaluating them. They await the global dynamic trigger scheduler object,
which is responsible for resuming them during the trigger evaluation
step in the 'act' eval region. Once the trigger is set, they await the
dynamic trigger scheduler once again, and then get resumed during the
resumption step in the 'act' eval region.

This changeset brings support for accesses like:
class Cls#(type TYPE1);
TYPE1::some_method();
endclass
It is done by delaying dot resolution on type parameters until they get
resolved by V3Param, and doing a more thorough reference skip.
In DFG DfgVertex::width() is only defined for vertices representing
packed values, which DfgVertex::hash() used to violate. The only
non-packed values at the moment are DfgVarArray, which is a
DfgVertexVar, which are handled specially anyway, so this is easy to
fix.
Fixes#3682
In order to not leak signal names with --protect-ids, we simply make the
trigger dump function empty (this is a debug only construct).
Partial fix for #3689
The emitted SystemC types (e.g. sc_bv) are not interchangeable with
Verilator internal C++ types (e.g.: VlWide), so the variables themselves
are not interchangeable (but can be assigned to/from each other). We can
preserve correctness simply be not inlining any SystemC variables (i.e.:
don't simplify any 'sc = nonSc' or 'nonSc = sc' assignments). SystemC
types only appear at top level ports so this should have no significant
impact.
Fixes#3688
