Based on mingw-w64.
System modules on Windows have load config available. In fact, all applications using the default MSVC for crt have it. mingw-w64 provides the load config, but it also requires linker to use it and currently only LLD supports it. This MR does the same in winecrt0. We will need it on both ARM64 and ARM64EC targets to support ARM64X (which requires LLD for other reasons anyway).
-- v2: winecrt0: Use load config on all targets.
