We previously were defining _BSD_SOURCE right before including getopt.h. However, on mingw-w64, getopt.h is also transitively included by unistd.h, and unistd.h can be transitively included by many headers (recently, by some libc++ headers). Therefore, to be safe, we need to define _BSD_SOURCE before including any header. Thus do this in CMake. This fixes https://github.com/llvm/llvm-project/issues/76050.
