CMake: Enforce x86-64-v2 ISA level across all dependencies

Expand ISA level enforcement to ensure all components, including vcpkg
dependencies, are built with x86-64-v2 instruction set. This addresses
remaining compatibility issues where dependencies were potentially being
built with higher ISA levels.

Changes:
- Add dedicated x86-64-v2 toolchain file for vcpkg
- Set ISA flags for both main project and dependencies
- Ensure proper quoting of compiler flags
- Configure vcpkg to use consistent toolchain settings

The fix requires cleaning both build and vcpkg directories before
rebuilding:
rm -rf build/
rm -rf vcpkg_installed/
