Fix erroneous implicit conversions of VlWide (#7642) 
Change WDataInP/WDataOutP to be opaque handles types instead of aliases
to raw pointers. This subsequently eliminates needing an implicit cast
operator in VlWide, which is replaced with implicit constructors of
WDataInP/WDataOutP that can create a handle from a VlWide. This
eliminates some unsafe conversions that the previous implicit cast
operator unintentionally enabled (e.g. #7618). It also eliminates
having to insert ".data()" in various places int he generated code, which
simplifies internals (the only place ".data()" should be needed is in
calls to variadic functions where the expected type of the argument is
not WDataInP/WDataOutP).

The handles otherwise behave like pointers, implementing the minimal
amount of operators required to code the runtime. The handle is still
only a single pointer, and will be passed in registers as before, so
this patch should be performance neutral.

As part of this removed WData, which used to be an alias for EData.
All uses are now either EData*, WDataInP, WDataOutP, or VlWide directly.

V3Timing: pre-clear destructive event state before dynamic waits (#7340) 
When lowering dynamic event controls, destructive pre-clear updates were inserted with addHereThisAsNext() on the original node and then that node was replaced. This could leave leaked/orphaned nodes under leak-checking runs.

Build an explicit replacement stmt chain instead:
  [pre-clear stmts] -> trigger loop -> awaitResumption,
and replace the original control with the chain head. Keep the loop-only path unchanged when no destructive pre-clear is needed.

Add 15 new DFG peephole optimizations (#7553) 
- FOLD_SELF_SUB: x - x -> 0
- REMOVE_DIV_ONE / REMOVE_DIVS_ONE: x / 1 -> x (unsigned and signed)
- REMOVE_MUL_ZERO / REMOVE_MUL_ONE / REMOVE_MULS_ZERO / REMOVE_MULS_ONE:
  0 * x -> 0 and 1 * x -> x (unsigned and signed)
- REPLACE_NOT_LT/GTE/GT/LTE and their signed counterparts: eliminate a
  Not vertex by flipping the comparison operator

Test signals for the NOT-of-comparison GT/GTE variants use unique shift
amounts to prevent intra-pass CSE from merging their DfgGt/DfgGte vertices
with those produced when the complementary LT/LTE patterns fire, which
would otherwise trigger the !hasMultipleSinks() guard.

Remove multi-threaded FST tracing (#7443) 
Remove parallel (using the FST library writer thread) and offloaded
(separate Verilator internal thread) tracing (only used by FST). These
are not compatible with #6992, and #5806 should yield better performance
in all cases.

Consequently mark '--trace-threads' and '--trace-fst-thread' options as
deprecated

Optimize Ast read references in Dfg directly (#7354) 
Introduce a new DfgAstRd vertex, which holds an AstNodeExpr that is a
reference to a variable. This enables tracking all read references in
Dfg, which both enables more optimization, and allows inlining of
expressions in place of the reference more intelligently (e.g, when the
expression is only used once, and is not in a loop). This can get rid of
20-30% of temporary variables introduced in Dfg in some designs. Note
V3Gate later got rid of a lot of those, this is a step towards making
V3Gate redundant. The more intelligent expression inlining is worth ~10%
runtime speed on some designs.
