aiger2: Only fail for reachable undirected bufnorm helper cells
...
The aiger2 backend checks for unsupported cells during indexing. This
causes it to fail when `$connect` or `$tribuf` (as workaround for
missing 'z-$buf support) cells are present in the module.
Since bufnorm adds these cells automatically, it is very easy to end up
with them due to unconnected wires or e.g. `$specify` cells, which do
not pose an actual problem for the backend, since it will never
encounter those during a traversal.
With this, we ignore them during indexing and only produce an actual error
message if we reach such a cell during the traversal.

portarcs: Ignore all bufnorm helper cells
...
The `portarcs` pass was already ignoring `$buf` cells when loading
timing data, but now bufnorm will also emit `$input_port` and `$connect`
helper cells, which need to be ignored as well.

This also rolls back any added cells and wires, since we might have
added a lot of helper logic by the point we detect this.

verific: New -sva-continue-on-error import option
...
This option allows you to process a design that includes unsupported
SVA. Unsupported SVA gets imported as formal cells using 'x inputs and
with the `unsupported_sva` attribute set. This allows you to get a
complete list of defined properties or to check only a supported subset
of properties. To ensure no properties are unintentionally skipped for
actual verification, even in cases where `-sva-continue-on-error` is
used by default to read and inspect a design, `hierarchy -simcheck` and
`hierarchy -smtcheck` (run by SBY) now ensure that no `unsupported_sva`
property cells remain in the design.
