Version 7.4.5: [V8] Added AddPerformanceObject and SetTimerResolution to V8ScriptEngineFlags (GitHub Discussion #568); [V8] Enhanced execution and termination transitions, fixing GitHub Issue #560; optimized document code for string documents (GitHub Discussion #567); switched to Clang and C++20 on all platforms; added .NET 8 targets to test projects; updated API and build documentation. Tested with V8 12.3.219.12.
