cmd/link: use correct alignment in PE DWARF sections

Browse Source 
Set the correct section flags to insure that .debug_* sections are
using 1-byte alignment instead of the default. This seems to be
important for later versions of LLVM-mingw on windows (shows up on the
windows/arm64 builder).

Updates #46406.
