[Bug ld/22843] Provide dependency information from the linker similar to the compiler

The point of this request is to integrate the linker's dependency list with
Make and Ninja. The way the workflow would go (and already does for compilers)
is the following:

 - the linker gets invoked with a flag to write the dep file
 - it gets written to libresult.so.d (or somesuch)
 - _immediately_ after the process has finished, Make or Ninja loads the
contents of the file and stores it in their internal data storage
 - in case of Ninja, it immediately deletes the .d file after it has read it,
this makes a big performance difference on Windows

As can be seen, getting the dependency info in the correct format is necessary,
because it is immediately consumed. Needing to do a conversion means that
everyone who wants to use this feature needs to wrap all linker invocations in
a custom script.
