build-mingw-w64: Split out building tools to a separate script

This simplifies build-mingw-w64.sh. When building on native windows (where we also provide unprefixed tools, we can't have the yet incomplete compiler toolchain in $PATH when building the mingw-w64 tools. (Logically, build-mingw-w64-tools belong with build-llvm and install-wrappers; using the original system compiler to build tools that are supposed to run on the current machine, as opposed to the cross target, like when building the runtimes.)
