feat(swift): implement schema evolution compatible mode for fory swift

[chaokunyang]

Why?

Swift xlang compatible mode was missing key schema-evolution behaviors used by cross-language tests, so several compatibility scenarios were not covered end-to-end.

What does this PR do?

• Implements compatible-mode schema evolution in Fory Swift serialization/deserialization, including schema-hash-aware struct handling and field skipping for unknown/removed fields.
• Adds dynamic type-info handling for heterogeneous arrays and maps in compatible mode.
• Improves non-tracking reference canonicalization for collection/map elements when global reference tracking is enabled.
• Extends Swift type/meta plumbing (Context, Serializer, TypeResolver, SchemaHash, ForyTypeId) and macro output to align with xlang compatible encoding requirements.
• Reworks ForySwiftXlangPeer case handlers to round-trip major xlang scenarios through native Swift serializers (schema-consistent/compatible, polymorphism, nullable fields, refs/circular refs, unsigned).
• Expands Java SwiftXlangTest with explicit @Test entries so Maven Surefire discovers inherited xlang cases consistently.
• Updates a Swift unit test expectation to account for schema hash in the struct header.
