* [RISCV] Add generated RV64GC register descriptionRichard-Qin-X2026-08-071-2/+28
| | | | Add an RCC-owned build-time target description generator and the initial RV64GC register model. Keep ABI aliases separate from canonical MIR register spelling.

Introduce an immutable register topology for units, subregisters, classes, banks, and preserved masks. Bind instruction descriptors to this topology through TargetDescription so builders, cloning, and verification share one target-aware contract. Add the test-only TestTarget model and positive and negative target fact coverage.
