Tests: Consolidate format specific t_trace_* tests (#7216) 
Factor out test execution into t/trace_*_common.py, which defines
a 'run' functions. All related t_trace_*py tests call this function.

Behaviour is partially encoded in the file name, which must be of the
form: t_trace_complex_<variant>_<mode>_<format>*.py, where '<variant>'
determines tracing options (default/params/structs), '<mode>' is the
compilation mode (--cc/--sc), and '<format>' determines the trace format
(vcd/fst/saif).

The part of the test name after '<format>' does not influence the test
directly and can be free form. If used, explicit 'verilator_flags2' is
passed to the 'run' function.

Fix tracing of typedefed 1D packed arrays with --trace-structs (#7237) 
Used to incorrectly unroll 1D packed arrays of 'bit' or 'logic' into
elements when using --trace-structs if the array element type was given
via a typedef. Keep them as a single signal instead.

Fix soft cross-object constraint priority inversion (#7228) (#7233) 
Emit nested constraint setup tasks in depth-first order (deepest first)
so outer-scope soft constraints get higher priority per IEEE 18.5.13.

V3Randomize: Fix dist operator inside ConstraintIf blocks (#7221) (#7224) 
The lowerDistConstraints() function was not recursing into ConstraintIf
nodes, causing dist operators inside if-else blocks to remain unlowered
and trigger an internal error when ConstraintExprVisitor encountered them.

Fix by adding recursive handling of ConstraintIf nodes in lowerDistConstraints:
- Check for AstConstraintIf nodes before AstConstraintExpr
- Recursively process thensp() and elsesp() branches
- This ensures all dist operators are lowered regardless of nesting

Test case: t_randomize_dist_conditional.v demonstrates conditional dist:
    constraint c {
      if (randd) {
        x dist { 8'd0 := 1, 8'd255 := 3 };  // 25% / 75%
      } else {
        x dist { 8'd0 := 3, 8'd255 := 1 };  // 75% / 25%
      }
    }

Fixes #7221

Change array tracing to always dump left index to right index (#7205) 
Also add array bounds and struct/union member counts to trace pushPrefix
(not used by vcd/fst/saif). Together these improve consistency in some
waveform formats.
