Internal: Refactor AstAssignAlias (#6280) (#6473) 
Rename AstAssignAlias to AstAlias and make it derive from AstNode
instead of AstNodeStmt.

Replace AstAlias with AstAssignW in V3LinkDot::linkDotScope, which is
the last place we need to be aware of the alias construct. Using
AstAssignW dowstream enables further optimization while preserving the
same functionality.

Internals: Improve cppcheck flow and fix up issues (#6311) 
Added cppcheck-suppressions.txt in the repo root. You can add new
patterns in there instead of having to parse the XML output.

Also configure to add the -D__GNUC__ preprocessor macro, which makes it
understand UASSERT (it understands the 'noreturn' function attribute).

Added some case by case specific suppressions and fixed up other code,
especially in V3Ast*h and V3Dfg*.h, including code generated by astgen
that had some no-ops that irks cppcheck.

One thing it does not seem to like is `const` class members with default
initializers in the class. It will assume that's always the value, even
if overridden in the constructor. We had few so removed them.

With that a lot of files in `src/` are now clean or only have a handful
of issues. Therefore, I have also deleted cppcheck_filtered, and made it
produce human readable output straight to the terminal.

Regarding cleaning up the reported nits, I kind of got bored after
V3[A-E] so pausing here. Apologies for the merge conflicts.

Tested with cppcheck 2.13.0

Remove AstJumpLabel (#6221) 
Remove AstJumpLabel

AstJumpGo now references one if its enclosing AstJumpBlocks, and
branches straight after the referenced block.

That is:

```
JumpBlock a {
   ...
   JumpGo(a);
   ...
}
// <--- the JumpGo(a) goes here
```

This is sufficient for all use cases and makes control flow much easier to
reason about. As a result, V3Const can optimize a bit more aggressively.

Second half of, and fixes #6216
