Tobias Tebbi 21b585165f Reland "[torque] refactor: use -tq only in filenames derived from .tq files"
This is a reland of 64caf2b0b2

Original change's description:
> [torque] refactor: use -tq only in filenames derived from .tq files
>
> This is to establish a naming rule for Torque-generated files:
> - If the file is called foo/bar-tq..., then it is derived from a
>   file foo/bar.tq
> - Otherwise it doesn't belong to a specific .tq file.
>
> So far, we attached -tq to all Torque-generated file names, where it
> sometimes corresponded to a .tq file name and sometimes not.
> It is not necessary to add -tq to file names to indicate that they are
> Torque-generated, since they are already in a directory called
> torque-generated, and we always refer to them as
> "torque-generated/filename", so there is no confusion even though some
> files now have the same name as a corresponding hand-written file, for
> example factory.cc.
