sv: support assignments within expressions - Add support for assignments within expressions, e.g., `x[y++] = z;` or `x = (y *= 2) - 1;`. The logic is handled entirely within the parser by injecting statements into the current procedural block. - Add support for pre-increment/decrement statements, which are behaviorally equivalent to post-increment/decrement statements. - Fix non-standard attribute position used for post-increment/decrement statements.

tests: Run async2sync before sat and/or sim to handle $check cells Right now neither `sat` nor `sim` have support for the `$check` cell. For formal verification it is a good idea to always run either async2sync or clk2fflogic which will (in a future commit) lower `$check` to `$assert`, etc. While `sim` should eventually support `$check` directly, using `async2sync` is ok for the current tests that use `sim`, so this commit also runs `async2sync` before running sim on designs containing assertions.
