feat(resolver): port SecurityAdvisoryPoolFilter::filter

Implement the security advisory pool filter end to end, plus the
remaining actionable wirings it unblocked.

- Unify the PartialSecurityAdvisory|SecurityAdvisory union as the
  PartialOrFullSecurityAdvisory enum and make the advisory types Clone,
  so advisories can be collected and stored; Pool.security_removed_versions
  now carries the union. This also unblocks PoolOptimizer's clone of the
  security-removed versions.
- Thread the filter result through run_security_advisory_filter/build_pool
  as anyhow::Result.
- Introduce typed PlatformRepositoryHandle and pass platform repos as
  handles through determine_requirements instead of &PlatformRepository.
- Wire RuleSetGenerator's is_unacceptable_fixed_or_locked_package check
  and UpdateCommand's non-locked installed-packages branch.
