Subject: [PATCH] std.debug: add TargetInfo function which returns the default
 SelfInfo

If one overrides `SelfInfo` in their `root.debug`, it is no longer possible
to refer to the default `SelfInfo` that the std.debug uses.

This allows the developer to still refer to the std's default without
copying the SelfInfo zig files to their project.
