Remove x86-64 ISA compatibility flags and toolchain
Remove the x86-64 instruction set architecture (ISA) compatibility flags and
associated toolchain file that were setting CPU architecture compatibility
levels. This simplifies the build system by removing the custom ISA flag
handling and x86-64-v2 option.
Changes:
- Remove x86-64 ISA flags configuration block from CMakeLists.txt
- Delete unused x86-64-toolchain.cmake file
- Remove CITRON_USE_X86_64_V2 option
