go.mod, cmd/tailscaled, ipn/localapi, util/osdiag, util/winutil, util/winutil/authenticode: add Windows module list to OS-specific logs that are written upon bugreport

* We update wingoes to pick up new version information functionality
  (See pe/version.go in the https://github.com/dblohm7/wingoes repo);
* We move the existing LogSupportInfo code (including necessary syscall
  stubs) out of util/winutil into a new package, util/osdiag, and implement
  the public LogSupportInfo function may be implemented for other platforms
  as needed;
* We add a new reason argument to LogSupportInfo and wire that into
  localapi's bugreport implementation;
* We add module information to the Windows implementation of LogSupportInfo
  when reason indicates a bugreport. We enumerate all loaded modules in our
  process, and for each one we gather debug, authenticode signature, and
  version information.

Fixes #7802
