fix: add ggml-blas support for macOS build

Fix the following error that occurred when loading the extension:
Error: dlopen(./dist/ai.dylib, 0x000A): symbol not found in flat namespace '_ggml_backend_blas_reg'

Updated the Makefile to link against libggml-blas.a and include -lggml-blas in LDFLAGS for macOS builds. This enables BLAS support, potentially improving performance on macOS platforms.
