Internals: Refactor generate construct Ast handling (#6280) (#6470) 
Internals: Refactor generate construct Ast handling (#6280)

We introduce AstNodeGen, the common base class of AstGenBlock,
AstGenCase, AstGenFor, and AstGenIf, which together represent all SV
generate constructs. Subsequently remove AstNodeFor, AstNodeCase
(AstCase is now directly derived from AstNodeStmt) and adjust internals
to work on the new representation.

Output is identical modulo hashes do to changed AstNode type ids, no
functional change intended.

Step towards #6280.

Internals: Fix remaining cppcheck errors (#6319) 
Fixed the non const-related issue and added suppressions for the const
ones. With that `make cppcheck` should be clean.

Fix dynamic NBAs with automatic vars (#4696) 
This patch addresses two issues with NBAs in non-inlined functions/tasks:
- If the NBA writes to a local automatic var, the var could cease to exist before the NBA executes. This is normally addressed by fork dynscopes (#4356), but NBA-to-fork transformation happens way after `V3Fork` (in `V3Timing`). To solve this, we put NBAs that write to locals under forks in `V3Fork` already. This way, such locals will be put in dynscopes, and will still exist after the task containing the NBA exits.
- The above change means that any writes in forks other than `fork..join` should be handled by `V3Fork`. Thus, in `V3SchedTiming`, we only have to worry about read references, so we can simply copy all remaining locals. Because we copy, lifetimes are not an issue. This fixes a bug that allowed assignment intravals to be overwritten if they go out of scope in the containing function.
