[HAL/AMDGPU] Separate SVM facts from peer flags

Record AMDGPU SVM/HMM memory-system facts as cold capability state instead of deriving peer behavior from SVM_ACCESSIBLE_BY_DEFAULT. System info now keeps SVM support, default pageable access, and XNACK mode grouped together, and each physical device records SVM direct-host access plus selected fine/coarse device-local placement facts.

Add a generic SHARED_VIRTUAL_ADDRESS device capability and map it to the existing topology edge bit without letting it select NATIVE buffer modes. AMDGPU now maps SVM_SUPPORTED to SHARED_VIRTUAL_ADDRESS and SVM_ACCESSIBLE_BY_DEFAULT to UNIFIED_MEMORY, while peer addressability and coherency stay owned by per-pool/per-link refinement.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Eenvironment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
