Update c2pa-rs to 0.92.0-rc.1

Changes

• Bump the native library to c2pa-v0.92.0-rc.1 in c2pa-native-version.txt, docs/project-contributions.md, docs/release-notes.md and the perf baseline metadata.

• Breaking: remove the legacy APIs that c2pa-rs 0.92.0 drops:

  • load_settings() (also removed from the c2pa package exports)
  • Builder.from_archive()
  • format_embeddable()

  Use Settings/Context and Builder(...).with_archive(...) instead. format_embeddable has no Python replacement yet.

• Update tests:

  • from_archive callers now use Builder({}).with_archive(...).
  • Delete tests that only exercised the removed APIs. The existing with_archive tests cover the equivalent behavior.
  • Remove two perf scenarios that depended on from_archive, along with their baseline entries.

• Update docs to say these APIs were removed in 0.92.0.
