Jannis Harder 83dd99efb7 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.
