cmd/internal/obj: generate SEH aux symbols for windows/amd64
This CL updates the Go compiler so it generate SEH unwind info [1] as a
function auxiliary symbol when building for windows/amd64.
A follow up CL will teach the Go linker how to assemble these codes
into the PE .xdata section.
Updates #57302
