Bug 1542830: Part 4 - Modify mozglue to use new untrusted modules interfaces; r=mhowell

* At this point our DLL blocking infra is complicated enough that I decided to
  bite the bullet and move all of this code out of `mozglue/build` and into its
  own subdirectory, `mozglue/dllservices`.
* We delete the original `UntrustedDllsHandler` code which is now obsolete.
* We implement mozglue's `LoaderObserver`:
** When this observer registers itself with the launcher process API, it
   receives a vector containing all saved records of loaded DLLs that happened
   until that moment.
** This code handles profiler labels and stackwalking suppression.
** Once a load has completed, we either pass the load on to XUL for further
   processing, or save it for later if XUL is not initialized yet.
* mozglue has its own `ModuleLoadFrame` implementation for the legacy blocklist.
* `DllServicesBase` is updated to support the new interfaces.
* We implement `FallbackLoaderAPI` for `plugin-container`, `xpcshell`, and
  any other non-`firefox` processes that do not have a launcher process
  providing a loader API.
* We add some wide to UTF8 conversion functions.
