Migrate CordbModule caches to SHash

[hoyosjs]

Part of #11466.

CordbSafeHashTable uses a fixed bucket count, causing lookups to degrade as debugger caches grow. This migrates the high-cardinality, non-enumerated CordbModule class, function, and native-code caches to an SHash-backed table.

The new table preserves internal reference ownership, process-lock assertions, lazy allocation, function-version replacement, and linear-time cleanup. It also hashes the full pointer width on 64-bit hosts.

COM-enumerated and EE/DAC tables remain unchanged because they depend on cursor, iteration, or storage-layout behavior that requires separate work.

There are no intended breaking changes.

Pull request overview

This PR introduces an SHash-backed hashtable wrapper for right-side debugger (Cordb*) caches and migrates CordbModule’s class/function/native-code caches from the fixed-bucket CordbSafeHashTable to the new CordbSHashTable, keeping the existing internal-ref ownership and RS lock assertions.

Changes:

• Generalize RSInitHolder::TransferOwnershipToHash to work with multiple hashtable types (not just CordbSafeHashTable).
• Add CordbSHashTable + CordbSHashTraits (pointer-element SHash wrapper) with 64-bit key hashing that incorporates the high 32 bits.
• Switch CordbModule’s m_classes, m_functions, and m_nativeCodeTable to CordbSHashTable and remove the old fixed bucket-count ctor initialization.
