clang:libclang_rt.builtins-xxx.a supports builtin

Browse source 
1. enable CONFIG_BUILTIN_COMPILER_RT  to built libclang_rt.builtins-xxx.a and no longer use the compiler's built-in
2. Modify clang version acquisition to get two decimal points
3. It has been ported to support four architectures: ARM, ARM64, RISCV, and x86_64, among which ARM has been validated
