feat(il2cpp): read member names, string literals and metadata versions 24 and 27 (#5326)

Browse Source 
* feat(il2cpp): read member names, string literals and metadata versions 24 and 27

Adds field, property, event and parameter names with their owners, managed string literals, and the version 24 and 27 header layouts to inspect_il2cpp_metadata, with filtered pages for the new collections. Member decoding yields between row batches like the other row readers.

* fix(il2cpp): bound metadata expansion and query parameter owners

* test(il2cpp): cover nonempty property and event tables

"Inspect a local Unity IL2CPP global-metadata.dat (versions 29, 31 and 39). Default summary retains complete Evidence and returns artifact identity, version and counts and parent_evidence_id. Query inspect_analysis_view kind il2cpp-metadata, collection sections/images/types/methods, with exact indices or names, fields and pagination. Types also accept image_indices, namespaces and declaring_types; methods accept declaring_types. Filters intersect and empty arrays select none. Each row always keeps index, scoped to its artifact SHA-256 and collection; page offsets count matching rows in metadata order. Explicit detail complete returns all rows. Reads existing files, with 256 MiB input and 64 MiB encoded-report guards and one active inspection per reader. Unsupported versions and malformed metadata return reasons. Type declaring_type is derived from nestedTypes; native code addresses and runtime behavior remain unknown.",
