This commit introduces basic Application Binary Interface (ABI) support in gccrs for the unadjusted and platform-intrinsic variants. The changes involve updating the ABI utility class in rust-abi.h and rust-abi.cc to recognize and handle these ABI specifiers, which are used to control how types are passed and laid out.
