  Log Message:
  -----------
  [lld][COFF] Provide unwinding information for Chunk injected by /delayloaded

For each symbol in a /delayloaded library, lld injects a small piece of
code to handle the symbol lazy loading. This code doesn't have unwind
information, which may be troublesome.

Provide these information for AMD64.

Thanks to Yannis Juglaret <yjuglaret at mozilla.com> for contributing the
unwinding info and for his support while crafting this patch.

Fix #59639
