Fix relative list regressions

[p-x9]

Summary

• require MachOKit 0.52.2, which fixes the remaining Objective-C metadata omission in MachOKit
• remove the local symbol(...) compatibility extension now provided by MachOKit
• resolve relative list offsets against the cache that actually backs the target Mach-O
• preserve every relative-list entry matching an image index instead of returning only the first entry
• aggregate all matching method, property, and protocol lists in both MachOFile and MachOImage paths
• add a regression test covering multiple relative method lists for _UTCoreType

Root cause

The cache lookup introduced with the relative-list implementation conflated the cache containing the resolved Mach-O with the cache backing the list data. Separately, the image-index lookup selected only the first matching relative-list entry, while the pre-0.8 implementation combined all matching lists.

This caused Objective-C metadata to be partially omitted when a class had multiple relative lists or when the Mach-O and list data were located in different dyld cache files. MachOKit 0.52.1 also retained a related omission bug, so this package now requires 0.52.2.

Impact

Callers of classInfo(in:) can once again obtain all matching relative methods, properties, and protocols instead of silently losing later lists.
