abi: Template symbol parameters are either Qualified or Mangled.

[ibuclaw]

An example of a QualifiedName found in a TemplateArg can be seen when dump the symbols of this compiled program: https://github.com/dlang/phobos/blob/31e1b462d2311f9d8cecb33172b28eab587b255d/std/parallelism.d#L43-L77

Also symbol parameters are prefixed with their symbol length, as per bugzilla 3043.

Implementation and Notes: https://github.com/dlang/dmd/blob/15b3ee1603b7dcc0317ba63c54f77ee9718f90e4/src/ddmd/dtemplate.d#L8323-L8331

Thanks.

If we want to document non-D symbols as template parameters, we should extend it by

    $(B S) $(GLINK Number) $(GLINK ExternallyMangledName)

or even use this instead of the MangledName rule. The symbol compression in dlang/dmd#5855 prefers to reencode the name and type, so this would rather remove the MangledName rule instead.
