[1/3] widl: Pass type attributes from write_array_tfs to write_pointer_description. Take 2.

[Dmitry Timoshkov]

This allows to differentiate strings and write appropriate rpc type
(FC_C_C[W]STRING instead of FC_[W]CHAR).

This version of the patch limits write_array_tfs() to pass attributes
to write_pointer_description() only for strings and avoids unwanted
changes to other pointer types.
