tools/x86_64: Add LLVM target definitions
Summary:
- Added LLVM target definitions (`LLVM_ARCH`, `LLVM_CPU`, `LLVM_ABI`) to
`arch/x86_64/src/cmake/Toolchain.cmake` and
`arch/x86_64/src/common/Toolchain.defs`
- These definitions are necessary for compatibility with LLVM-based
toolchains and ensure proper target architecture, CPU, and ABI settings
Impact:
- Enables support for LLVM-based toolchains when building for x86_64
architecture
- No functional changes for existing GNU-based toolchains
- Improves maintainability by centralizing LLVM-specific configurations in
the toolchain files
