widl: Fix nested parameterized types C / short name output.
We append type->name from each parameter when constructing the c_name of parameterized type. When the parameter is itself a parameterized type this field contains C++-like name, with template brackets.
Instead this precomputes the names of parameterized types whenever they are used as a parameter. In this case the format is the same as the C name, except that __C is used as a namespace separator, instead of _C, and that there's no namespace or abi prefix included.
Shorthands need to be applied too, altough they have to match the __C.
