Add FFI bindings for libunwind on ppc64le Linux, matching the existing pattern for x86, x86_64, and aarch64 architectures. This enables stack unwinding on PowerPC 64-bit little-endian systems. The implementation includes all PPC64 register definitions from libunwind-ppc64.h (GPRs, FPRs, condition registers, vector/AltiVec registers) and uses libc's getcontext() for context capture as libunwind does on this platform.
