Fixes #4490.
Fixes #4435.

There are three parts to this:

1. Ensure that transient language profiles associated with a disabled
   keyboard are enumerated correctly
2. Stop trusting `LocaleNameToLCID` when it returns a transient language
   id, as it sometimes reports out-of-date values. We don't need to
   trust it in these cases anyway, because we have already collected the
   relevant transient language data from Win8Languages.
3. Finally, setting the profile GUID to `GUID_NULL` is simply tidyup,
   which does not have impact on the running code currently but makes
   state consistent.

I believe that part 2 fixes #4435 because the symptoms are identical.
But as I am unable to repro that particular issue on my machine thus
far, that is an assumption. Hopefully we can get a good test result from
@MakaraSok.
