Support LLVM 22

[ahueck]

Add LLVM 22 support, update dimeta to v0.5.1, and update CI actions and dependencies.

Key Changes

• LLVM 22 compatibility: Update MemInstFinder, MemOpVisitor, and MemOpInstrumentation to handle API changes in LLVM 22 (llvm::scope_exit, getArgOperand vs getOperand for lifetime intrinsics, findAllocaForValue signature)
• CI matrix: Add LLVM 22 to lit-suite, typeart-bench, ad-bench, and omp-bench workflows
• GitHub Actions updates: Bump actions/checkout to v6, actions/upload-artifact to v7, coverallsapp/github-action to v2.3.6; migrate coverage jobs to ubuntu-24.04
• Dependency updates: dimeta v0.4.0 → v0.5.1 (adds DIMETA_ENABLE_FLANG), abseil 20250814.1 → 20250814.2
• Runtime: Change type file missing and recorded types log levels from LOG_WARNING/LOG_INFO to LOG_DEBUG; use config::EnvironmentStdArgs::types constant instead of hardcoded string
• RuntimeData.h: Guard SANITIZE_ADDRESS definition with !defined(SANITIZE_ADDRESS) to prevent redefinition; set value to 1
• RuntimeInterface.h: Remove commented-out typeart_get_containing_type declaration
