CLI: detect MinGW-flavored static libraries
Ideally on Windows, static libraries look like "foo.lib". However, CMake and other build systems will unfortunately produce static libraries that instead look like "libfoo.a". This patch makes Zig's CLI resolve "-lfoo" arguments into static libraries that match this other pattern. This patch fixes an issue with zig-bootstrap where it won't find the LLVM, Clang, and LLD libraries.
